1.1 Inclusions

This Standard specifies requirements for the management of hearing loss prevention programs (HLPPs) designed to protect workers from occupational hearing loss.

Following principles set out in CSA-Z45001, this Standard specifies requirements for

a) management commitment, leadership, and participation;
b) assignment of roles and responsibilities;
c) identification and quantification of noise hazards;
d) selection and application of controls;
e) provision of protection (e.g., HPDs);
f) training, monitoring, and measurement (e.g., noise exposure and
audiometric testing);
g) documentation; and
h) continuous improvement and management review.

1.2 Exclusions

The following subjects are not specifically addressed in this Standard:

a) psychological and other non-auditory health effects; and
b) non-occupational exposure except as it contributes to occupational exposure.

1.3 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.1 

This Standard describes construction and test requirements for new non-rail-bound diesel-powered, self-propelled machines for use in gassy underground coal mines. Note: The working environment of gassy mines is characterized by the presence of methane gas and combustible dust.

1.2

This standard does not specify requirements for safety, other than those directly related to the risk of ignition which may lead to an explosion.

This standard is supplementary to, or amendatory of CSA standards M424.0 Underground Mining Mobile Equipment – General Requirements and M424 Diesel powered machines for use in non-gassy underground mines.

Note: See CAN/CSA-M424.0 for general vehicle design, safety and performance requirements.

Note: See CAN/CSA-M424.2 for diesel engine design, safety and emissions requirements.

1.3

Braking system performance requirements and proof tests are not included in the Scope of this Standard, except from the standpoint of the reduction of fire and explosion hazards.

Note: See CAN/CSA-M424.3 for brake construction, stopping performance, and test requirements.

1.4

The standard atmospheric conditions (relating to the explosion characteristics of the atmosphere) under which it may be assumed that the engine may be operated are:

temperature -20°C to +60°C

pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and   

air with normal oxygen content, approximately 21% v/v.

1.5

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but

not required; and “may” is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.

1.1

This Standard describes the technical requirements and procedures necessary for the design; performance and testing of new or unused diesel engines for use in non-gassy underground mines.

Note: See CAN/CSA-M424.1 for additional explosion-proof construction and performance requirements for diesel-powered machines for use in gassy underground coal mines.

1.2

Machine design and performance requirements are not included in this scope of the standard.

Note: See CAN/CSA-M424.0 and M424.4 for general underground mining vehicle performance requirements.

1.3

Braking system performance requirements and proof tests are not included in the Scope of this Standard.

Note: See CAN/CSA-M424.3 for brake construction, stopping performance, and test requirements.

not required; and “may” is used to express an option or that which is permissible within the limits of the standard.

This Standard describes minimum performance criteria for the service braking system, secondary braking system, and parking system for rubber-tired, self-propelled underground mining machines.

1.1

This standard provides minimum braking system performance for rubber-tired, self-propelled underground machines, and test criteria by which machine braking system performance may be verified.

Notes:

Additional requirements for brake systems on machines used in coal and gassy underground mines are found in M424.1.

Additional requirements for dynamic and continuous retarding systems are found in M424.4.

1.2

If a value for measurement as given in this Standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.

1.3

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but

not required; and “may” is used to express an option or that which is permissible within the limits of the standard.

This standard applies to new or unused wheeled or tyred, self-propelled, non-rail-bound, mobile machines for use in underground mines.

This Standard describes the technical aspects and procedures necessary for the design, performance, and testing of core design and safety requirements.

This standard is a product family standard and covers general requirements only. For each kind of underground mining mobile equipment, the product standard is composed by this standard and the relevant specific standard.

For utility / Service / Support machines, this document only includes provisions to address the risks associated with the mobility (movement of the whole machine from one location to another). Risks for the additional functions (e.g. scaling, concrete spraying, bolting, charging drilling attachment) are not covered in this document.
