Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-307 - Safety standards for agriculture › INDOOR OPERATIONS › Part T - Electrical › Section 296-307-36010 - Definitions that apply to this part

Current through Register Vol. 24-14, July 15, 2024
The following definitions apply to this part:
Acceptable
.
An installation or
					 equipment that is acceptable to the department and meets the requirements of
					 this section. An installation or equipment is acceptable if:
(1) It is accepted, certified, listed,
				  labeled, or otherwise determined to be safe by a nationally recognized testing
				  laboratory; or
(2) For
				  installations or equipment that no nationally recognized testing laboratory
				  accepts, certifies, lists, labels, or determines to be safe, it is inspected or
				  tested by another federal agency, or by state, municipal, or other local
				  authority responsible for enforcing occupational safety provisions of the
				  National Electrical Code, and complies with the provisions of the National
				  Electrical Code, and complies with the provisions of the National Electrical
				  Code as applied in this section; or
(3) For custom-made equipment or related
				  installations that are designed, fabricated for, and intended for use by a
				  particular customer, it is determined to be safe for its intended use by its
				  manufacturer on the basis of test data that the employer keeps and make
				  available for our inspection.
Accepted
.
An installation that
					 has been inspected and certified by a nationally recognized testing laboratory
					 to meet specified plans or procedures of applicable codes.
Bonding jumper
.
A reliable
					 conductor that provides the correct electrical conductivity between metal parts
					 that are required to be electrically connected.
Branch circuits
.
The part of a
					 wiring system extending beyond the final overcurrent device protecting the
					 circuit. A device not approved for branch circuit protection, such as thermal
					 cutout or motor overload protective device, is not considered as the
					 overcurrent device protecting the circuit.
Certified
.
Equipment that:
(a) Has been tested and found by a nationally
				  recognized testing laboratory to meet nationally recognized standards, or to be
				  safe for use in a specified manner; or
(b) Is a kind whose production is
				  periodically inspected by a nationally recognized testing laboratory;
				  and
(c) Bears a label, tag, or
				  other record of certification.
Exposed
.
A live part that can be
					 accidentally touched or approached nearer than a safe distance. This term
					 applies to parts that are not suitably guarded, isolated, or insulated.
Fixed equipment
.
Equipment
					 fastened or connected by permanent wiring methods.
Ground
.
A conducting connection,
					 whether intentional or accidental, between an electrical circuit or equipment
					 and earth, or to some conducting body that serves in place of the earth.
Grounded
.
Connected to earth or
					 to some conducting body that serves in place of the earth.
Isolated
.
Equipment that is not
					 readily accessible except through special means of access.
Labeled
.
Equipment that has an
					 attached label, symbol, or other identifying mark of a nationally recognized
					 testing laboratory that:
(a) Makes
				  periodic inspections of the production of such equipment; and
(b) Whose labeling indicates compliance with
				  nationally recognized standards or tests to determine safe use in a specified
				  manner.
Qualified person
.
A person who is
					 familiar with the construction and operation of the equipment and the hazards
					 involved.
Note 1:
Whether an employee is considered a
					 "qualified person" depends on various circumstances in the workplace. It is
					 possible and likely for an individual to be considered "qualified" with regard
					 to certain equipment in the workplace, but "unqualified" as to other
					 equipment.
Note 2:
An employee undergoing on-the-job
					 training and who, in the course of such training, has demonstrated an ability
					 to perform duties safely at his or her level of training and who is under the
					 direct supervision of a qualified person is considered a qualified person for
					 the performance of those duties.
Shock hazard
.
Exists at an
					 accessible part in a circuit between the part and ground, or other accessible
					 parts if the potential is more than 42.4 volts peak and the current through a
					 1,500 ohm load is more than 5 milliamperes.
Weatherproof
.
Constructed or
					 protected so that exposure to the weather does not interfere with successful
					 operation. Rainproof, raintight, or watertight equipment may be considered
					 weatherproof where weather conditions other than wetness, such as snow, ice,
					 dust, or temperature extremes, are not a factor.
