1.1 Objective

1.1.1 Protection standards for welding, cutting, and allied processes

This Standard provides minimum requirements and recommendations to protect persons who work in an environment affected by welding, cutting, and allied processes from illness and injury and to prevent damage to property arising from the installation, operation, and maintenance of equipment used in these processes.

1.1.2 Elements of a welding health and safety program

This Standard specifies the elements of a welding health and safety program (see Clause 4) that are necessary to implement the requirements and recommendations specified in this Standard.

1.2 Applicability

1.2.1 Standard for personnel in welding, cutting, and allied process environments

This Standard applies to all personnel working in an environment affected by welding, cutting, and allied processes.

1.2.2 Application of standard to welding and allied processes

The requirements of this Standard apply to the processes illustrated in the Master chart of welding and allied processes (see Figures A.1 and A.2).

Note: One should consult the authority having jurisdiction, together with this Standard, to ensure compliance to mandatory legislative requirements.

1.3 Exclusions

This Standard does not apply to

a) the design or manufacture of welding or safety equipment; and

b) storage, use, and handling of natural gas and propane in accordance with CSA B149.1 and CSA B149.2.

1.4 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 (nonmandatory) to define their application.

1.5 Units of measurement

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

1.1 Inclusions

This standard addresses

a)    the scope of practice for various levels or types of Power Engineer certifications; and

b)   the method to classify facilities in relation to the Power Engineering requirements by calculating a facility rating using a standardized unit (kW). This facility rating shall be used to prescribe facility staffing and attendance requirements with respect to levels of Power Engineer certifications (prescriptive-based method).

1.2 Exclusions

This standard does not address

a)    technical and physical design requirements of boiler, refrigeration, compressor and steam prime mover equipment;

b)   equipment and facility physical infrastructure requirements;

c)    boilers used in connection with an open-type hot water heating system having no intervening valves between the boiler and any direct vent, preventing any pressure build up above atmospheric pressure;

d)   siting or location of facilities;

e)    scopes of work for personnel or professional certifications not related to operations; and

f)    installation, maintenance, or repair.

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 Inclusions

Cette norme aborde :

a)    le champ d’exercice des différents niveaux ou types de certification des ingénieurs en énergie; et

b)   la méthode permettant de classer les installations en fonction des exigences en matière d’ingénierie énergétique en calculant une cote d’installation à l’aide d’une unité normalisée (kW). Cette cotation de l’installation doit être utilisée pour prescrire les exigences en matière de dotation en personnel et de présence à l’installation en ce qui concerne les niveaux de certification des ingénieurs en énergie (méthode prescriptive).

1.2 Exclusions

Cette norme n’aborde pas :

a)    les exigences techniques et physiques de la conception des chaudières, des équipements de réfrigération, des compresseurs et des appareils moteurs à vapeur;

b)   les exigences en matière d’équipement et d’infrastructure physique des installations;

c)    les chaudières utilisées dans le cadre d’un système de chauffage à eau chaude de type ouvert ne comportant pas de vannes intermédiaires entre la chaudière et un évent direct, ce qui empêche toute augmentation de la pression au-dessus de la pression atmosphérique;

d)   l’implantation ou la localisation des installations;

e)    les cahiers des charges pour le personnel ou les certifications professionnelles qui ne sont pas liés à l’exploitation; et

f)    l’installation, l’entretien ou la réparation.

1.3 Terminologie

Dans cette norme, le terme « doit » indique une exigence, c.-à-d., une prescription que l’utilisateur est obligé à respecter pour assurer la conformité à la norme; « devrait » indique une recommandation ou ce qu’il est conseillé, mais non obligatoire de faire; et « peut » indique une possibilité ou ce qu’il est permis de faire.

Les notes qui accompagnent les articles ne comprennent pas de prescriptions ni de recommandations. Elles servent à séparer du texte les explications ou les renseignements qui ne font pas proprement partie de la norme.

Les notes au bas des figures et des tableaux font partie de ceux-ci et peuvent être rédigées comme des prescriptions.

Les annexes sont qualifiées de normatives (obligatoires) ou d’informatives (facultatives) pour en préciser l’application.

 

1.4 Unités de mesure

Les valeurs indiquées en unités SI sont les unités d’enregistrement aux fins de la présente norme. Les valeurs indiquées entre parenthèses ne sont données qu’à titre d’information et de comparaison.
