AWAY FROM HEAT, SPARKS, OPEN FLAME OR ANY OTHER IGNITION SOURCE. USE
EXPLOSION-PROOF ELECTRICAL (VENTILATING, LIGHTING AND MATERIAL HANDLING)
EQUIPMENT.
ADVICE ON GENERAL OCCUPATIONAL HYGIENE:
EATING, DRINKING AND SMOKING SHOULD BE PROHIBITED IN AREAS WHERE THIS
MATERIAL IS HANDLED, STORED AND PROCESSED. WORKERS SHOULD WASH HANDS AND
FACE BEFORE EATING, DRINKING AND SMOKING. REMOVE CONTAMINATED CLOTHING AND
PROTECTIVE EQUIPMENT BEFORE ENTERING EATING AREAS. SEE ALSO SECTION 8 FOR
ADDITIONAL INFORMATION ON HYGIENE MEASURES.

| SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION | |
CONTROL PARAMETERS:
OCCUPATIONAL EXPOSURE LIMITS:
INGREDIENT NAME EXPOSURE LIMITS
HYDROGEN CALIFORNIA PEL FOR CHEMICAL CONTAMINANTS
(TABLE AC-1) (UNITED STATES). OXYGEN
DEPLETION [ASPHYXIANT].
ACGIH TLV (UNITED STATES, 3/2019). OXYGEN
DEPLETION [ASPHYXIANT]. EXPLOSIVE POTENTIAL.
APPROPRIATE ENGINEERING CONTROLS:
USE ONLY WITH ADEQUATE VENTILATION. USE PROCESS ENCLOSURES, LOCAL EXHAUST
VENTILATION OR OTHER ENGINEERING CONTROLS TO KEEP WORKER EXPOSURE TO
AIRBORNE CONTAMINANTS BELOW ANY RECOMMENDED OR STATUTORY LIMITS. THE
ENGINEERING CONTROLS ALSO NEED TO KEEP GAS, VAPOR OR DUST CONCENTRATIONS
BELOW ANY LOWER EXPLOSIVE LIMITS. USE EXPLOSION-PROOF VENTILATION
EQUIPMENT.
ENVIRONMENTAL EXPOSURE CONTROLS:
EMISSIONS FROM VENTILATION OR WORK PROCESS EQUIPMENT SHOULD BE CHECKED TO
ENSURE THEY COMPLY WITH THE REQUIREMENTS OF ENVIRONMENTAL PROTECTION
LEGISLATION. IN SOME CASES, FUME SCRUBBERS, FILTERS OR ENGINEERING
MODIFICATIONS TO THE PROCESS EQUIPMENT WILL BE NECESSARY TO REDUCE
EMISSIONS TO ACCEPTABLE LEVELS.
INDIVIDUAL PROTECTION MEASURES:
HYGIENE MEASURES:
WASH HANDS, FOREARMS AND FACE THOROUGHLY AFTER HANDLING CHEMICAL PRODUCTS,
BEFORE EATING, SMOKING AND USING THE LAVATORY AND AT THE END OF THE WORKING
PERIOD. APPROPRIATE TECHNIQUES SHOULD BE USED TO REMOVE POTENTIALLY
CONTAMINATED CLOTHING. WASH CONTAMINATED CLOTHING BEFORE REUSING. ENSURE
THAT EYEWASH STATIONS AND SAFETY SHOWERS ARE CLOSE TO THE WORKSTATION
LOCATION.
EYE/FACE PROTECTION:
SAFETY EYEWEAR COMPLYING WITH AN APPROVED STANDARD SHOULD BE USED WHEN A
RISK ASSESSMENT INDICATES THIS IS NECESSARY TO AVOID EXPOSURE TO LIQUID
SPLASHES, MISTS, GASES OR DUSTS. IF CONTACT IS POSSIBLE, THE FOLLOWING
PROTECTION SHOULD BE WORN, UNLESS THE ASSESSMENT INDICATES A HIGHER DEGREE
OF PROTECTION: SAFETY GLASSES WITH SIDE- SHIELDS.
SKIN PROTECTION:
HAND PROTECTION:
CHEMICAL-RESISTANT, IMPERVIOUS GLOVES COMPLYING WITH AN APPROVED STANDARD
SHOULD BE WORN AT ALL TIMES WHEN HANDLING CHEMICAL PRODUCTS IF A RISK
ASSESSMENT INDICATES THIS IS NECESSARY. CONSIDERING THE PARAMETERS
SPECIFIED BY THE GLOVE MANUFACTURER, CHECK DURING USE THAT THE GLOVES ARE
STILL RETAINING THEIR PROTECTIVE PROPERTIES. IT SHOULD BE NOTED THAT THE
TIME TO BREAKTHROUGH FOR ANY GLOVE MATERIAL MAY BE DIFFERENT FOR DIFFERENT
GLOVE MANUFACTURERS. IN THE CASE OF MIXTURES, CONSISTING OF SEVERAL
SUBSTANCES, THE PROTECTION TIME OF THE GLOVES CANNOT BE ACCURATELY
ESTIMATED.
BODY PROTECTION:
PERSONAL PROTECTIVE EQUIPMENT FOR THE BODY SHOULD BE SELECTED BASED ON THE
TASK BEING PERFORMED AND THE RISKS INVOLVED AND SHOULD BE APPROVED BY A
SPECIALIST BEFORE HANDLING THIS PRODUCT. WHEN THERE IS A RISK OF IGNITION
FROM STATIC ELECTRICITY, WEAR ANTISTATIC PROTECTIVE CLOTHING. FOR THE
GREATEST PROTECTION FROM STATIC DISCHARGES, CLOTHING SHOULD INCLUDE
ANTI-STATIC OVERALLS, BOOTS AND GLOVES.
OTHER SKIN PROTECTION:
APPROPRIATE FOOTWEAR AND ANY ADDITIONAL SKIN PROTECTION MEASURES SHOULD BE
SELECTED BASED ON THE TASK BEING PERFORMED AND THE RISKS INVOLVED AND
SHOULD BE APPROVED BY A SPECIALIST BEFORE HANDLING THIS PRODUCT.
RESPIRATORY PROTECTION:
BASED ON THE HAZARD AND POTENTIAL FOR EXPOSURE, SELECT A RESPIRATOR THAT
MEETS THE APPROPRIATE STANDARD OR CERTIFICATION. RESPIRATORS MUST BE USED
ACCORDING TO A RESPIRATORY PROTECTION PROGRAM TO ENSURE PROPER FITTING,
TRAINING, AND OTHER IMPORTANT ASPECTS OF USE. RESPIRATOR SELECTION MUST BE
BASED ON KNOWN OR ANTICIPATED EXPOSURE LEVELS, THE HAZARDS OF THE PRODUCT
AND THE SAFE WORKING LIMITS OF THE SELECTED RESPIRATOR.
