Significance and Use
4.1 Vapor inhalation is the primary hazard encountered in the use of chlorinated solvents. The greatest potential for over exposure to these solvent vapors occurs where the employee is exposed to the high concentrations of vapor that may be found in confined areas. The seriousness of this hazard is often underestimated by those performing this type of work.
4.3 Many of these areas are considered as permit-required confined spaces as defined by OSHA (29 CFR 1910.146). The determination of the applicability of these requirements is the responsibility of the user.
4.5 This practice does not address all of the requirements contained in the OSHA confined spaces standard. Development and implementation of training programs, recordkeeping, and other additional requirements of the OSHA standard are the responsibility of the user.
1.1 This practice covers recognized procedures necessary to protect the health and safety of workers required to enter confined spaces. These procedures are particularly applicable to entry into the confined areas associated with the use of halogenated organic solvents.
1.2 Confined areas addressed in this practice include, but are not limited to: vapor degreasers, cold cleaning tanks, storage vessels, tank cars and trucks, van trailers, ships or barges, pits or sumps, and unventilated rooms.
1.4 Although this practice describes specific safety steps to be taken for entry into confined spaces, it is not intended to preclude the use of any additional measures that may be deemed necessary for a particular situation.
