6. Accidental Release Measures <br />Adequately ventilate area of leak or spill. Wear appropriate personal protective equipment (PPE), <br />as specified in Section 8. Isolate hazard area to keep unprotected personnel from entering. Stop <br />the leak if possible. Contain and recover liquid when possible. Neutralize spilled liquid with <br />alkaline materials (soda ash, lime). Then absorb the neutralized liquid with an inert material, such <br />as vermiculite, sand, or earth and place recovered material in an approved, compatible chemical <br />waste container. Do not use combustible materials such as cardboard or saw dust as an <br />absorbent. Do not flush spilled acid to the sewer. EPA regulations require reporting spills and <br />releases to the soil, air and water, in excess of the reportable quantity (5,000 Ibs), to the National <br />Response Center, telephone number 1-800-424-8802. Reporting to the State Emergency <br />Response Commission (SERC) warning point and local authorities (911) is also required. <br />7. Handling and Storage <br />Store in a cool, dry, ventilated storage area with acid resistant floors and good drainage. Protect <br />from physical damage. Keep out of sunlight and direct heat, water and incompatible materials. Do <br />not wash out container and use it for other purposes. When diluting, the acid should always be <br />added slowly to the water. Never use hot water and never add water to acid. Water added to acid <br />can cause uncontrolled boiling and splashing. Empty acid containers may be hazardous since <br />they retain acid residues of liquid and vapor. Observe all warnings and precautions stated on the <br />acid container label. Wear personal protective equipment when handling, opening containers and <br />using hydrochloric acid. <br />8. Exposure Control and Personal Protection <br />Airborne Exposure Limits: <br />OSHA Permissible Exposure Limit (PEL) 5 ppm (Ceiling) (7 mg/m) <br />NIOSH Relative Exposure Level (REL) 5 ppm (Ceiling) (7 mg/m) <br />ACGIH Threshold Limit Value (TLV) 2 ppm (Ceiling) (TWA) <br />NIOSH Immediately Dangerous Level (IDLH) 50 ppm <br />Ventilation: A system of local and/or general exhaust is recommended to keep exposure below <br />the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can <br />control the emissions of the acid at the source, preventing dispersion into the occupied area. <br />Personal Respirators (NIOSH Approved): If exposure limits are exceeded and engineering <br />controls are not feasible, a full face respirator with an acid gas cartridge may be worn up to 50 <br />times the permissible exposure limit (PEL). For emergencies or instances where the exposure <br />levels are not known, use full face, positive pressure, air supplied respirator.. WARNING! Air <br />purifying respirators do not provide protection in oxygen deficient atmospheres. <br />Skin Protection: Rubber or neoprene gloves and additional protection including impervious <br />boots, apron, or coveralls, are needed in areas of unusual exposure to prevent skin contact. <br />Eye Protection: Use safety glasses with side shields, chemical safety goggles and/or a full face <br />shield where splashing is possible. Maintain eye wash fountain and quick drench facilities (safety <br />shower) in work areas. <br />9.
