Elevating Devices Safety Regulation.
Guidelines Part 14 - General requirements
G14.2-1 Standard - Tower cranes
Issued September 1999; Editorial Revision February 1, 2008
Regulatory excerpt
Subsection 14.2 of the OHS Regulation ("Regulation") states:
(6) A tower, hammerhead crane or self erecting tower crane must meet the requirements of CSA Standard Z248-2004, Code for Tower Cranes.
(7) A portal, tower or pillar crane must meet the requirements of ANSI Standard ASME B30.4-2003, Portal, Tower, and Pillar Cranes.
Purpose of guideline
The purpose of this guideline is to clarify the scope and application of CSA Standard Z248-2004, Code for Tower Cranes and ANSI Standard ASME B30.4-2003, Portal, Tower, and Pillar Cranes.
Application of the Regulation
Both subsections 14.2(6) and 14.2(7) set out standards applicable to tower cranes. However, the application of each subsection is determined by the difference in the "Scope" description in each standard. The scope of the CSA Standard Z248-2004 makes it applicable to all tower cranes, irrespective of use or industry service. The scope of the ANSI Standard ASME B30.4-2003, as it applies to tower cranes, is limited to a tower crane not used in construction.
G14.3 Identification
Issued September 1999; Editorial Revision February 1, 2008
Regulatory excerpt
Section 14.3(2) of the OHS Regulation ("Regulation") states:
Each major interchangeable structural component of a crane or hoist must be uniquely identified and must be legibly marked to enable confirmation that the component is compatible with the crane or hoist.
Purpose of this guideline
The purpose of this guideline is to provide information on identification of interchangeable structural components for cranes or hoists.
Identification
This requirement is applicable to, but not limited to, lattice boom mobile cranes and tower cranes. Generally the lattice boom on a mobile crane is made up of several boom sections connected together. The configuration of the boom can be varied to meet the needs of the particular lifting task. The crane manufacturer will specify what components must be used to make up the boom to achieve any particular allowable boom configuration. Some components will be interchangeable, and may be shared between similar equipment from the same manufacturer.
Similarly, a tower crane is made up using tower and jib sections. The configuration of the crane at each setup can be varied, within limits set by the manufacturer, to suit the needs of the location. As with the mobile crane boom, it is possible to interchange components from similar equipment. To ensure that only the components that the manufacturer approves for use with the configuration are used, it is necessary to identify the components.
A catalogue or part number is sufficient for the purpose of identifying compatibility, but there are also strict inspection and certification requirements for these components. Unique identification allows cross-referencing with the inspection or certification documents to ensure the component in use is the component inspected or certified. Ideally, the identifier on each component will be a serial number provided by the manufacturer. However, interchangeable components are usually only identified by the manufacturer with a part number. This satisfies one reason for the requirement (identifying interchangeable components) but not the need to correlate documents to specific components. An additional and unique identifier is required. The identifier must be legible and durable.
G14.5 Rated capacity indication
Issued September 1999; Editorial Revision February 1, 2008
Regulatory excerpt
Section 14.5(1) of the OHS Regulation ("Regulation") states:
Subject to subsection (3), the rated capacity of a crane or hoist system must be permanently indicated on the superstructure, hoist and load block of the equipment.
Purpose of guideline
The purpose of this guideline is to provide information on the term 'superstructure' and supporting structure.
Superstructure and supporting structure
With respect to a bridge crane, the "superstructure" refers to the bridge girders. It is not necessary to mark the safe working load on the crane runways or the supporting structure for the bridge crane runways.
G14.13 Inspection, maintenance, and repair
Issued September 1999; Editorial Revision February 1, 2008
Regulatory excerpt
Section 14.13(1) of the OHS Regulation ("Regulation") states:
Each crane and hoist must be inspected and maintained at a frequency and to the extent required to ensure that every component is capable of carrying out its original design function with an adequate margin of safety.
And section 14.13(3) of the Regulation states:
Any repair to load bearing components of a crane or hoist must be certified by a professional engineer or the original equipment manufacturer as having returned the component to a condition capable of carrying out its original design function with an adequate margin of safety.
Purpose of guideline
The purpose of this guideline is to provide information about the frequency of inspections and load bearing components.
Frequency of inspections
Inspection and maintenance must be done to the extent and frequency recommended
by the original equipment manufacturer or the applicable standard referenced
in Part 14 of the Regulation, whichever is more stringent, and as required
based on the frequency and nature of use. (See section 14.2(1) of the Regulation
for a list of the relevant standards.)
Load bearing components
"Load bearing components" include any component that transfers load through the crane or hoist to the surface supporting the crane or hoist.
G14.29 Operator protection
Issued September 1999; Editorial Revision February 1, 2008; Editorial Revision May 1, 2008
Regulatory excerpt
Section 14.29 of the OHS Regulation ("Regulation") states:
The operator of a crane or hoist must be protected against hazardous conditions such as falling or flying objects and excessive heat or cold that could adversely affect the health or safety of the operator.
And section 26.13.1(1) of the Regulation states:
(1) Protective guards must be provided and used on a self-loading log transporter or similar equipment unless
a) it is not practicable to do so, and
b) the absence of guards does not pose a hazard to the equipment operator.
Purpose of guideline
The purpose of this guideline is to discuss the application of section 14.29 to self-loading log trucks under section 26.13.1(1).
Self-loading log trucks
Section 26.13.1(1) of the Regulation provides an exception to the requirements of section 14.29 that is applicable to self-loading log trucks and similar equipment. Under section 26.13.1(1) the equipment may only be used without overhead protective guards if the absence of such guards does not present a risk of injury to the operator.
Guidelines Part 14 - Equipment operation
G14.34.1 Operator certification
Issued January 1, 2007; Editorial Revision May 3, 2007
Regulatory excerpt
Section 14.34.1 of the OHS Regulation ("Regulation") provides:
On and after July 1, 2007, a mobile crane, tower crane or boom-truck must be operated only
(a) by a person with a valid operator's certificate issued by a person acceptable to the Board, and
(b) in accordance with any conditions stipulated on the certificate by the issuing person.
Purpose of guideline
This guideline identifies the association WorkSafeBC considers to be "a person acceptable to the Board" under section 14.34.1. It also specifies the types of equipment operators who are required to be certified and provides an overview of the certification program.
Background
Prior to 2007, the Regulation required that crane operators have an appropriate trade qualification, be an indentured apprentice, or have a qualification determined by the Industry Training and Apprenticeship Commission ("ITAC"). For employers and prime contractors, ensuring crane operators were appropriately trained, qualified, and competent has been very challenging. While there have been a number of programs available for training and apprenticeship, there has been no easy means to evaluate crane operator qualifications or competence levels. With the dissolution of ITAC compliance with the Regulation industry-wide evaluation of operators became even more difficult.
After wide industry consultation, a program for assessment and documentation of crane operators' competency was developed. The British Columbia Association for Crane Safety (BCACS) was then formed to administer the program and issue crane operator certificates.
Person acceptable to WorkSafeBC
Operators of mobile cranes, tower cranes, and boom trucks must possess a valid operator's certificate issued by a person acceptable to WorkSafeBC. The BCACS is currently the only person acceptable to WorkSafeBC to issue operators' certificates for these types of cranes.
The BCACS includes representatives of employers and workers from many of the industries that use this type of equipment, as well as representatives of WorkSafeBC and other government agencies. The BCACS has developed a program for assessing mobile and tower crane and boom truck operator competency and the issuing of a "proof of competency" document (operator's certificate) to a person who successfully completes the assessment processes.
WorkSafeBC would also consider other persons to be acceptable issuers of operators' certificates under section 14.34.1 if they meet criteria established by WorkSafeBC. This would include criteria around the assessment of candidates and the qualifications of assessors.
Types of equipment operators covered
Section 14.34.1 applies to operators of all mobile cranes, boom trucks, and tower cranes with a rated capacity equal to or greater than five tons or with a boom length of 25 feet or greater. WorkSafeBC considers this equipment to include the following:
Mobile Cranes and Boom Trucks:
As described in
- CSA Standard Z150-1998, Safety Code for Mobile Cranes
- ANSI Standard ANSI/ASME B30.5-2004, Mobile and Locomotive Cranes
- ANSI Standard ANSI/ASME B30.22-2005, Articulating Boom Cranes
As described in
- CSA Standard Z248-2004, Code for Tower Cranes
- ANSI Standard ASME B30.4-2003, Portal, Tower, and Pillar Cranes
The certification program
BCACS will issue operators' certificates to competent operators following the completion of a competency assessment. BCACS does not offer crane operator training, nor is a specific training program required. Training, if required, may be undertaken through an employer's in-house program or through a third party program provider or training agency.
Operators' certificates will be specific to certain types of equipment as set out on the operator's certificate. Operators who are certified for one type of equipment will be restricted to operating that type of equipment until they pass an assessment for another type as well.
Interim certificate
For all types of equipment, new candidates may qualify for an interim certificate if they pass a basic theory test. This certificate will be temporary and will restrict the types of situations under which the candidate may operate a crane, and require the candidate to operate under the direct supervision of a certified operator.
Theory assessment
Every operator of a mobile crane, tower crane, or boom truck must pass an assessment on the theory, operating principles, and regulatory requirements relating to the type of equipment they intend to operate. For certain types of equipment, the successful completion of an assessment will permit the operator to operate that equipment with full independence. For other types of equipment, there may be restrictions, such as a requirement to work under the direct supervision of a certified operator, until a practical assessment is completed.
Practical assessment
For certain types of equipment, in order to operate the crane independently without direct supervision, the operator will be required to demonstrate their operating skills in a practical test on the equipment.
Implementation
The BCACS program begins in January 2007. By July 1, 2007, operators covered by section 14.34 must have obtained an appropriate certificate and be operating in accordance with that certificate or be registered with the BCACS and in the process of obtaining an appropriate certificate.
See http://www.bcacs.ca for further details of its certification program.
Guidelines Part 14 - Mobile cranes, boom trucks and aerial ladder cranes
G14.64(3) Definition of "duty cycle work"
Issued August 16, 2000; Editorial Revision February 1, 2008
Regulatory excerpt
Section 14.64(3) of the OHS Regulation ("Regulation") states:
A crane being used for duty cycle work is exempt from the requirements of subsection (1) if the load applied to the crane is safely below the rated capacity of the crane and if the possibility of an unexpected overload does not exist.
Purpose of guideline
The purpose of this guideline is to provide information on the concepts of 'duty cycle work,' and 'safely below the rated capacity of the crane.' The guideline also discusses pulling and repositioning a pile, and support activities.
Duty cycle work
"Duty cycle work" means the use of a crane to do dragline, clamshell, dynamic compaction, or pile driving work, or with an electromagnet such as for handling scrap metal. Pile extraction using a vibrating pile extraction device is also considered duty cycle work. In duty cycle operations the loads are generally known and/or can be maintained "safely below the rated capacity" for the crane. Pile extraction without a vibrating extraction device is not to be considered within the scope of the exemption of section 14.64(3), as the load applied to the crane cannot be assured of being safely below the rated capacity of the crane.
Safely below the rated capacity of the crane
The phrase "safely below the rated capacity of the crane" means the total load being handled should not exceed 75% of the rated capacity of the crane. The rated capacity of a mobile crane varies with the configuration of the crane, such as the length of boom installed, and the boom angle/load radius. Good craning practice requires the operator to accurately know the weight of the total load to be lifted, and the rated capacity of the crane for the full range of movement of the lifted load. Typically the lifting tasks needed to support duty cycle work should involve loads of less than 50% of the rated capacity of the crane.
Pulling and repositioning a pile
When starting to drive a pile, occasionally the lower end of the pile will drift or move off of its intended position to the extent the crew will need to stop driving that pile, pull the pile back out, and reposition it before resuming driving that pile. Typically the need to do this will arise once or twice a shift, and the decision to pull and reposition the pile will be made before about 10% of the intended pile depth in the ground has been achieved. Pulling a pile in these circumstances is not typically considered a "pile extraction" operation. Generally the friction load from the soil acting on such a short length of a pile which has just been driven should be low relative to the weight of the pile. Provided the total lift needed in these circumstances can be reasonably determined to be safely below the rated capacity of the crane, it may be done by the crane being used for driving the pile without installing a load weight indicating device on that crane.
Support activities
During operations such as clam shell dredging and pile driving there are generally other lifting tasks to be performed to support the pile driving or dredging function. For example, piling material may need to be off-loaded from a truck or repositioned on the worksite or a welder or air compressor may need to be repositioned. Provided such support activities involve lifts of known weight that are safely below the rated capacity of the crane, they may be done by the crane being used for the duty cycle work without installing a load weight indicating device on that crane.
A crane on site not being directly used in the duty cycle application must conform to the requirements of sections 14.64(1) and (2) of the Regulation.
G14.71 Good engineering practices
Issued February 1, 2008
Regulatory excerpt
Section 14.71 of the OHS Regulation ("Regulation") states:
(1) A mobile crane or boom truck must be inspected at least once every 12 months in accordance with good engineering practice to ensure it meets(a) the crane or boom truck manufacturer's specifications,
(2) A mobile crane or boom truck must not be used after an inspection under subsection (1) unless a professional engineer certifies it is safe for use on the basis of that inspection.
(b) the requirements of the applicable design or safety standard specified in section 14.2, and
(c) the requirements of this Regulation
Purpose of guideline
The purpose of this guideline is to outline some of the factors that should be considered when determining if an inspection has been conducted in accordance with "good engineering practice" under section 14.71. It also provides information on who is authorized to certify that the inspection has been done and that the crane or boom truck is safe for use.
The concept of good engineering practice
An annual inspection and certification of a mobile crane or boom truck is required by the Regulation. This inspection and certification is to be done in accordance with good engineering practice. The concept of good engineering practice as it applies to section 14.71 means inspection, assessment, repair (if necessary), and certification of the equipment and it is to be done in consideration of
- Applicable regulations, safety codes, and standards
- Manufacturer's instructions for operation, inspection, maintenance, servicing, and repair
- Operating, maintenance, and service records
Who may do the certification
Certification must be done by a professional engineer. If the inspection, assessment, and any necessary repair work is done in BC, the engineer, as required by the Engineers and Geoscientists Act, must be licensed to practice in BC. If this work is being done outside BC, for example in Alberta, the engineer must be licensed to practice in that jurisdiction.
The inspection and certification process
The employer or owner of the equipment should consult the certifying engineer in advance to arrange the location of the inspection, testing, and necessary repair work, and to ensure qualified people and adequate facilities are used. Generally the "hands on" part of inspection, testing, and repair will be done by mechanics, service technicians, non-destructive testing (NDT) technicians, and other qualified workers as necessary (for example, welders), working under the direction of the certifying engineer. Inspection and certification requires assessment of the "critical components," meaning the structural, mechanical, and control system components that affect the safe operation of the equipment. The specific identity of these components will vary from one type of equipment to another, depending on the design and configuration of the equipment.
The frequency of inspections of individual components and the extent of inspections, including dismantling, assessment, and NDT or other testing, will be determined by the certifying engineer. The factors relevant in making these determinations include
- Requirements of the applicable regulations, safety codes, and standards
- The equipment manufacturer's specifications and instructions
- The certifying engineer's familiarity with the particular design and model of equipment, including known reliability problems or component problems
- Previous inspection history and results
- Age of the equipment and number of hours of use
- Circumstances of use of the equipment (for example, heavy duty vs. light use) and any known incidents since the last certification
- The general condition of the equipment
- The environment in which the equipment has been used (for example, a corrosive environment vs. a clean, dry shop or yard area)
- The available use, service, inspection, and maintenance records
- The certifying engineer's knowledge of the overall effectiveness of the service and maintenance program
Based on the outcomes of the inspection, the certifying engineer will determine any necessary repair work.
The certification document will include a statement that the equipment is "safe for use" at the completion of the inspection and any necessary repair. This means that the equipment should then reasonably be expected to perform safely until the next inspection and certification is required if operated according to the manufacturer's instructions.
If the certifying engineer deems it necessary to provide a restricted certification statement (for example, that some components are currently acceptable for safe use but will likely require replacement or renewal before the next annual inspection), the engineer will ensure the owner or employer is made aware of these concerns. He or she will also note the concerns on the equipment inspection and maintenance records. It is not acceptable for the certifying engineer to provide a certification when there are outstanding deficiencies affecting the safe performance of the equipment or compliance with the Regulation.
Guidelines Part 14 - Tower cranes
G14.88(5) Alternative means of jib access
Issued February 1, 2008
Regulatory excerpt
Section 14.88 of the OHS Regulation ("Regulation") defines "access" as follows:
-
(1) A tower crane must have a fixed ladder installed in or on the mast to provide access to the jib and crown of the crane.
(2) The ladder under subsection (1) must meet the following requirements:
-
(a) the ladder must be able to support two 1.1 kN (250 lbs.) point loads between any two consecutive points where the ladder is attached to the crane;
(b) there must be a minimum horizontal distance of 15 cm (6 in.) between the rungs and the object to which the ladder is attached;
(c) landing platforms must be provided at least every 9 m (30 ft.) on the ladder;
(d) each section of the ladder must be offset horizontally from adjacent sections or the landing platforms must have trap doors;
(e) if a section of the ladder has a climb exceeding 6 m (20 ft.) in length, that section of ladder must have a ladder safety cage 68 cm to 76 cm (27 in. to 30 in.) in diameter or a ladder safety device must be used.
(4) The walkway referred to in subsection (3) must meet the following requirements:
-
(a) the walkway must be at least 30 cm (12 in.) wide and constructed with a non-skid surface;
(b) a handline, which is approximately 1 m (39 in.) above the level of the walkway, and a midline must be provided on both sides of the walkway not more than 30 cm (12 in.) out from the edge of the walkway and supported at intervals not exceeding 3 m (10 ft.);
(c) the handline and midline referred to in paragraph (b) must be wire rope of at least 1 cm (3/8 in.) diameter;
(d) if it is not practicable to provide handlines in accordance with paragraph (b), alternative means of fall protection, such as a horizontal lifeline system, must be provided in accordance with the requirements of Part 11 (Fall Protection) and must be set out in the fall protection plan.
(6) The climbing space of a tower crane mast must be clear of protruding objects and must provide a safe and unobstructed passage.
(7) A written fall protection plan, which addresses the requirements of fall protection when a person is operating, inspecting, servicing and maintaining the tower crane, must be developed and implemented.
Purpose of guideline
The purpose of this guideline is to provide information on
- The functions of the walkway required by section 14.88(3) & (4)
- Possible alternatives where walkways as specified by section 14.88(3) & (4) are not practicable
- An outline of the issues that typically need to be addressed when designing and implementing alternative safe means of access
For some tower cranes it may not be practicable to attach a walkway to the jib in a manner that would meet the requirements of section 14.88(3) & (4). For example, in some cases, there may be a walkway that can extend only as far as the trolley drive assembly, and on others it may not be feasible to fit a walkway at all.
Under section 14.88(5), other options for access can be considered, as long as they provide a safe means of access.
The function of the walkway
When designing safe means of access as alternatives to walkways it is important to recognize the functions or purposes served by walkways.
The walkway is intended to provide a means of safe access by a worker to all points along the jib. Access along the full length is needed for the purposes of inspections, maintenance, and any repairs on the jib or its support system. The walkway also provides access to the operator's cab, if mounted on the jib. In addition, it may provide an emergency access route if it is necessary to rescue a worker from the jib.
The CSA Standard Z248-2004 Code for Tower Cranes lists the types of inspections that must be done on the components of the crane, and their frequency. Inspections typically done from the walkway include
- Daily inspections of load trolley ropes, load hoist ropes that can reasonably be expected to be used during the shift, and their points of attachment
- Weekly inspections of structural pins and keepers, trolley rollers and tracks, gear shaft and belt drives, sheaves, bushings, pins, all rope attachments, pendant lines, cable clips, thimbles, and ferrules
- Monthly inspections of all running ropes, the jib structure, sheaves, bearings, and mounts
If the crane will be in place for an extended period of time, annual inspections are needed of the jib structure using nondestructive testing methods, all load carrying equipment (including sheaves, blocks, rings, shackles and hooks), and all wire ropes.
Possible alternatives to walkways
When provision of a walkway required by section 14.88(3) & (4) is not practicable on a tower crane there may be a number of other options for inspection and maintenance of components. Examples include
- For self erect cranes, lowering the jib to allow inspection and maintenance of jib components
- Use of an elevating work platform to access the jib area
- Use of a walkway narrower than specified in section 14.88(4), in combination with a horizontal lifeline along the jib
- Use of a work platform (basket) attached to the tower crane trolley, in combination with a personal fall arrest system. Note: European Standard EN14439:2006 Cranes-Safety-Tower Cranes requires both a basket attached to the trolley, and a walkway with side protection or a horizontal lifeline along the full length of the jib.
Issues that need to be addressed with alternative means of access
When designing and implementing a means of alternative access it is essential to ensure issues such as those listed below are addressed. The issues listed under item A would apply in all circumstances. Those listed under item B are more specific to work platforms attached to trolleys. Neither list is intended to be complete as in the final analysis a hazard assessment specific to the equipment needs to be done and appropriate protective measures implemented.
A. Issues of general application
- Communication procedures and equipment that will allow safe use of the access system.
- Assurance that any work platform or walkway used provides firm, non-slip footing.
- The means of compliance with the requirements for personal fall protection in Parts 11 and 13 of the Regulation.
- The means of inspection and certification of the device, in compliance with section 14.77 (Structural inspection) of the Regulation, if the device is part of the tower crane.
- An emergency procedure and means of rescuing a worker in the event that the access system fails, or the worker becomes incapacitated.
- Lockout of the energy supply to the tower crane in accordance with the requirements of Part 10 (Lockout) of the Regulation, as required for inspection and maintenance.
- Where applicable, guarding meeting the provisions of CSA Standard Z248-2004, Code for Tower Cranes, as required by section 14.2(6) of the Regulation.
- Instructions for use of the system and the training of workers.
B. Additional issues specific to work platforms attached to trolleys
- The means of compliance with certain provisions of CSA Standard Z248-2004, Code for Tower Cranes. (Among other things, for trolley systems, the Standard sets out requirements for braking the trolley, the means to prevent the trolley from becoming detached in the event of wheel or axle breakage or sideloading, and the means of stopping the outward movement of the load trolley in the event of trolley drive rope breakage.)
- The design and fabrication of the work platform and the means of attaching it to the trolley. (The platform should be designed and fabricated by the crane manufacturer specifically for the crane on which it is used, and be permanently marked with the manufacturer's information, the rated capacity, a part number, and the number of occupants for which it is designed (at 115 kg (250 lbs)/occupant). The system for attaching the platform to the trolley will need to ensure the platform is securely attached and remains level when occupied. If a platform system is built by another party, it will need to be accompanied by an engineering certificate and drawings that address the engineering issues involved.)
- The means of compliance with section 14.21 (Fenders) of the Regulation. (This section requires that trolley wheels be fitted with fenders or guards if there is a possibility of injury to the worker from contact with trolley wheels moving along the rail.)
- The means of compliance with section 4.58 (Specifications for guards and guardrails) of the Regulation, as it applies to the platform.
- The means of guarding against shearing and entanglement hazards when the platform is traveled along the jib.
- The means of compliance with the requirements of Part 10 (Lockout) of the Regulation so that the platform is immobilized during servicing and inspection of machine parts, and the worker is protected from movement of any equipment while performing work.
- The means of safe access to and egress from the platform.
- The installation, operation, and inspection requirements for the trolley, including any additional requirements for the attached platform provided by the tower crane manufacturer or other applicable party. (Note: The instructions for use are to include a stipulation that no loads are to be handled by the crane while the platform is occupied.)
