COATINGSPRO MARCH 2015 33 WORK IT SAFE If your evaluation of the work area indicates that it may be classifed as a confned space, the respirator selection process should start with compliance with the OSHA Respiratory Protection Standard. Respiratory protection must be worn whenever you are working in a hazardous atmosphere. The appropriate respirator will depend on the contaminant(s) to which you are exposed and the protection factor (PF) required. Required respirators must be National Institute for Occupational Safety and Health (NIOSH)-approved, and medical evalu- ation and training must be provided before use. Single-Strap Dust Masks: These are usually not NIOSH-approved. They must not be used to protec t from hazardous atmospheres; however, they may be useful in provid- ing comfort from pollen or other allergens. Approved Filtering Facepieces (Dust Masks): These can be used for dust, mists, welding fumes, etc. They do not provide protection from gases or vapors. Do not use these for asbestos or lead; instead, select from one of the following respirators. Half-Face Respirators: These can be used for protection against most vapors, acid gases, and dust or welding fumes. Cartridges/filters must match contaminant(s) and be changed periodically. Full-Face Respirators: These are more protective than half-face r e spirator s . They can al s o b e us e d f or pr ote c tion a g a i n s t m o s t v a p o r s , a c i d g a s e s , a n d d u s t o r weldin g f um e s . The face shield pr ote c t s the face a n d e y e s f r o m i r r i t a n t s a n d c o n t a m i n a n t s . Car tridges/filter s must match contaminant(s) and be changed periodically. Loose-Fitting Powered-Air-Purifying Respirators (PAPR): These offer breathing comfort from a battery-pow- ered fan, which pulls air through filters and circulates air throughout the helmet/hood. They can be worn by most workers who have beards. Cartridges/filters must match contaminant(s) and be changed periodically. Self- Contained Breathing Apparatus (SCBA): This is used for entr y and escape from atmospheres that are consid- e r e d Im m e d iate ly D a n ge r o u s to L i f e a n d H e alth (IDLH) or that are ox ygen deficient. They use their own air tank. For more information, contact: OSHA, Genera l Industr y Standard is br idge painting. W here the OSH A classification of a work place is uncertain, it is considered good practice to follow the requirements of the General Industr y Standard. Employers should also be on notice that OSH A is likely to publish a final rule for a Confined Spaces in Construction Standard this month. T his rule is expected to impose many requirements found in the General Industr y Standard on construction work places. Confined Spaces Defined For workplaces that fall under the General Industry Standard, the confned space is defned as any space that is: • Large/so configured for bodily injury. The confined space must be large enough so the worker can fit his/her body into the work area. • Limited/restricted means of entry/ exit. Most confined spaces are not configured so that an employee can quickly and easily exit the work area. • Not designed for continuous employee occupancy. Most confined spaces are only entered to perform maintenance, repair, etc. They are not normally occupied by employees. For construction work places, paragraph ( b)(6) of 29 CFR 1926.21 (Safety Training and Education) defines a confined space as "…any space having a limited means of egress, which is subject to the accumulation of toxic or f lammable contaminants or has an ox ygen-deficient atmosphere. Confined or enclosed spaces include, but are not limited to, storage tanks, process vessels, bins, boilers, venti- lation or exhaust ducts, sewers, underground utility vaults, tunnels, pipelines, and open top spaces more than 4 feet [1.2 m] in depth, such as pits, tubs, vaults, and vessels." If your evaluation of the work area indicates that it may be classified as a confined space, the respira- tor selection process should start w ith compliance w ith the OSH A Respirator y Protection Standard. T his standard is the same on Construction or General Industr y (29 CFR 1926.103 Safety Watch
