8(a) Occupational Exposure Limits (OELs) (continued):
NE- None Established
1. OSHA Permissible Exposure Limits (PELs) are 8-hour TWA (time-weighted average) concentrations unless otherwise noted. A (C) designation denotes a
ceiling limit, which should not be exceeded during any part of the working exposure unless otherwise noted. A Peak is defined as the acceptable
maximum peak for a maximum duration above the ceiling concentration for an eight-hour shift. A skin notation refers to the potential significant
contribution to the overall exposure by the cutaneous route, either by contact with vapors or, of probable greater significance, by direct skin contact
with the substance. A Short Term Exposure Limit (STEL) is defined as a 15-minute exposure. Whish should not be exceeded at any time during the work
day, An Actual Level (AL) is used by OSHA and NIOSH to express a health or physical hazard. They indicate the level of a harmful or toxic
substance/activity, which requires medical surveillance, increased industrial hygiene monitoring, or biological monitoring. Action Levels are generally
set at one half of the PEL but the actual level may vary from standard to standard. The intent is to identify a level at which the vast majority of
randomly sampled exposures will be below the PEL.
2. Threshold Limit Values (TLV) established by the American Conference of Governmental Industrial Hygienist (ACGIH) are 8-hour TWA concentrations
unless otherwise noted. A Short Term Exposure Limit (STEL) is defined as the maximum concentration to which workers can be exposed for a short
period of time (15 minutes) for only four hours throughout the day with at least on hour between exposures. A “skin” notation refers to the potential
significant contribution to the overall exposure by the cutaneous route, either by contact with vapors or, of probable greater significance, by direct skin
contact with the substance. ACGIH-TLVs are only recommended guidelines based upon consensus agreement of the membership of the ACGIH. As
such, the ACGIH TLVs are for guideline use purposes and are not legal regulatory standards for compliance purposes. The TLVs are designed for use by
individuals trained in the discipline of the industrial hygiene relative to the evaluation of exposure to various chemical or biological substances and
physical agents that may be found in the work place.
3. The national Institute for Occupational Safety and Health Recommended Exposure Limits (NIOSH-REL)- Compendium of Policy and Statements. NIOSH,
Cincinnati, OH (1992). NIOSH is the federal agency designated to conduct research relative to occupational health and safety. As is the case with ACGIH
TLVs, NIOSHA RELs are for guideline purpose only and as such are not legal, regulatory limits for compliance purposes.
4. The “immediately dangerous to life or health air concentration values (IDLHs)” are used by NIOSH as part of the respirator selection criteria and were
first developed in the mid 1970’s by NIOSH. The Documentation for Immediately Dangerous to Life or Health Concentrations (IDLHs) is compilation of
the rationale and sources of information used by NIOSH during the original determination of 387 IDLHs and their sub sequential review and revision in
1994.
5. Inhalable fraction, The concentration of inhalable particulate for the application of this TLV is to be determined from the fraction passing a size-selector
with the characteristics defined in the ACGIH 2013 TLVs® and BEIs® (Biological Exposure Indices) Appendix D, paragraph A.
6. PNOR (Particulates Not Otherwise Regulated). All inert or nuisance dusts, whether mineral, inorganic, or organic, not listed specifically by substance
name are covered by a limit which is the same as the inert or nuisance dust limit 15 mg/m
3
for total dust and 5 mg/m
3
for the respirable fractions.
8(b) Appropriate Engineering Controls: Use controls as appropriate to minimize exposure to metal fumes and dusts during handling operations.
Provided general or local exhaust ventilation systems to minimize airborne concentrations. Local exhaust is necessary for use in enclosed or
confined spaces. Provided sufficient general/local exhaust ventilation in pattern/volume to control inhalation exposures below current exposure
limits
 Respiratory Protection: Seek Professional advice prior to respirator selection and use. Fallow OSHA respirator regulations (29 CFR
1910.134) and, if necessary, use only a OSHA-approved respirator. Select Respirator based on its suitability to provide adequate
worker protection for given working conditions, level of airborne contamination, and presence of sufficient oxygen. Concentration in
air of the various contaminants determines the extend of respiratory protection needed. Half-face, negative-pressure. Air-purifying
respirator equipped with p100 filter is acceptable for concentrations up to 10 times the exposure limit. Full-face, negative pressure, air
purifying respirator equipped with p100 filter is acceptable for concentrations up to 50 times the exposure limit. Protection by air-
purifying negative-pressure and powered air respirators is limited. Use a positive-pressure-demand, full-face, supplied air respirator or
self-contained breathing apparatus (SCBA) for concentrations above 50 times the exposure limit. If exposure is above IDLH (Immediate
dangerous to life or health) for any of the constituents, or there is a possibility of an uncontrolled release or exposure levels are
unknown, then use a positive-demanded, full-face, supplied air respirator with escape bottle or SCBA.
Warning! Air-purifying respirators both negative-pressure, and powered-air do not protect workers in oxygen-deficient atmospheres.
 Eyes: Wear appropriate eye protection to prevent eye contact. For operations which result in elevating the temperature of the
product to or above its melting point or result in the generation of airborne particulates, use safety glasses to prevent eye contact.
Contact lenses should not be worn where industrial exposures to this material are likely. Use safety glasses or goggles as required for
welding, burning, sawing, brazing, grinding or machining operations.
 Skin: Wear appropriate personal protective clothing to prevent skin contact. Cut resistant gloves and sleeves should be worn when
working with steel products. For operations which result in elevating the temperature of the product to or above its melting point or
result in the generation of airborne particulates, use protective clothing and gloves to prevent skin contact. Protective gloves should
be worn as required for welding, burning or handling operations. Contaminated work clothing must not be allowed out of the work
place.
 Other protective equipment: An eyewash fountain and deluge shower should be readily available in the work area.
