Purpose The purpose of these regulations and standards is co prescribe minimum requirements and standards for the maintenance of occupational health in places of employment in Pennsylvania. H. "Mist" shall mean liquid droplets suspended in air. I. "Place of employment" shall mean a location or site where an individual possesses employment in a trade, occupation, or profession for the sake of monetary gain. Section 2. Application (amended August 18, 1964) "Threshold Limit Value" shall mean the maximum average atmos These regulations and standards shall apply to every place of employment. pheric concentration of contaminant to which workers may be exposed for an eight hour work ing day. (These values are set forth in Table 1 Section 3. Definitions hereof, which table is a part of these regula tions. ) .. A. "Atmospheric contaminant" shall mean a harmful substance or material it! air usually occurring in the form of a dust, fume, gas, vapor, or mist. K. "Vapor" shall mean any liquid, except water, which when held in suspension in air w'ill revert to its original liquid state after release from heatf chemical action, or pressure conditions, B. "Department" shall mean the Department of j (added August 18, 1964) "Short-Term Limit" Health, Commonwealth of Pennsylvania. shall mean the maximum atmospheric concentra C. "Dust" shall mean finely divided solid particles /'// tion of a contaminant to which a workman may be dispersed in air and having been formed by mech- r , exposed for a specified short-time period.

"Fume" shall mean solid particles dispersed in there are sufficient recovery periods between air resulting from some chemical or physical episodes for recuperation. The daily average process that involved a change of state, such as exposure to the contaminant, including these combustion, sublimation, or evaporation and con episodes, shall be such that the threshold limit densation. value set forth in Table 1 shall not be exceeded. E. "Gas" shall mean a formless fluid occupying the (These values are set forth in Table 2 hereof, space of enclosure. which table is a part of these regulations.) F. "General or dilution ventilation" shall mean ventilation provided to dilute the concentration of dusts, fumes, gases, vapors, or mists in the atmosphere of all or parr of the place of employ ment. G. "Local exhaust ventilation" shall mean that type of ventilation in which suction is applied at the M.

Employer's Duties A. Every employer shall install and provide such control measures and protective equipment as is required for the protection of health, B. Every employer shall inform and periodically instruct his employees regarding known hazards and proper methods for utilizing industrial hy giene control measures which are provided. C. When it is necessary for an employer to provide protective equipment, such employer shall pro vide an approved means for cleaning and steriliz ing such protective equipment, and the employer shall cause such equipment to be maintained in a clean and sanitary condition. Respiratory equip ment shall not be passed from one man to another until such equipment is clean and sterilized. When filter or cartridge type respirators are used, such employee shall have such respirator for his own exclusive use. Respiratory equipment and replacement units shall be stored, when not in use, in approved containers. D. (amended August 20, 1963) When employees are exposed to compounds capable of causing occu pational disease by inhalation and/or skin or mucous membrane absorption, the department may require their employer to provide physical exam inations and other tests for them at periodic in tervals. Section 5. Threshold Limit Values and Short-Term Limits A. (amended August 18, 1964) No employee shall be exposed to atmospheric concentrations of con taminants which concentrations may give rise to occupational disease. Tables 1 and 2 shall be used for the determination of permissible levels. B. Exposures to atmospheric contaminants or ad verse environmental conditions not referred to in Section 5A shall be controlled when necessary to protect health. Section 6. Air Recirculation and Discharge A. No air front any local exhaust ventilation system may be recirculated without express approval by (he Department, B- The discharge of air from any exhaust system shall be such that no air contamination will enter any window, door, or other opening of any work area in quantities sufficient to create a health hazard to or in such area. Section 7. Confined Space (amended January 25, 1968) No individual shall be permitted to enter any con fined space unless another workman supplied with emergency protective equipment is stationed outside the confined space to summon help and to assist the workman and until one of the three following condi tions have been met: A. It has been ascertained by air sampling that the atmosphere in the confined space contains an adequate quantity of oxygen and that harmful atmospheric contaminants have been diluted to saft concentrations prior to and during occu pancy; or B. The workman is equipped with a supplied-air respirator of self-contained breathing apparatus, a safety harness, a safety line and protective clothing, where necessary; or C. It is ascertained that no harmful contaminants are present and mechanically induced dilution ventilation is used before entry and during occu pancy to insure an adequate quantity of oxygen in the confined space. Section 8. Housekeeping A. The interiors, exteriors, and environs of buildings w'here hazardous materials are used, stored, or handled, shall be cleaned and maintained in such a manner as to prevent harmful exposure to hazardous materials. B- Employees engaged in such cleaning operations and all others who may be exposed shall wear protective equipment as is required. The cleaning operations should be done by suction apparatus. C. Where wet processes are used, reasonable drain age should be maintained. False fl6rs, plat forms, mats, or other means of safe footing should be provided. Section 9. Labeling Adequate identification, warning, and caution labels shall be applied to all containers of hazardous chemicals, AA AT 350 otrrri ( > i 1 FA fttSKlii 1 iV.'..: i r . ilbUtinji PHP-Ch. 4-432 (amended August 17, 1965) REGULATIONS FOR THRESHOLD LIMITS Table 1.
