NONESafety Requirements
WARNING
IT IS THE RESPONSIBILITY OF THE OPERATOR TO OBTAIN AND OBSERVE THE MANUFACTURER'S MATERIAL SAFETY DATA SHEETS FOR CONSUMABLE MATERIALS. THESE CONTAIN INFORMATION SUCH AS, HAZARDOUS INGREDIENTS, PHYSICAL/CHEMICAL CHARACTERISTICS, FIRE, EXPLOSION, REACTIVITY, HEALTH HAZARD DATA, PRECAUTIONS FOR SAFE HANDLING, USE AND CONTROL MEASURES AND ALSO TO TAKE LOCAL REGULATIONS INTO CONSIDERATION.
WARNING
THE OPERATORS MUST ALWAYS WEAR THE PROTECTIVE CLOTHING SUPPLIED, WHICH INCLUDES EYE PROTECTION AND RUBBER GLOVES.
WARNING
IF SODIUM HYDROXIDE SOLUTION GETS INTO THE EYES, FULLY FLUSH THEM WITH CLEAN WATER AND THEN GET MEDICAL TREATMENT IMMEDIATELY.
WARNING
CAREFULLY ADD THE COMPOUNDS WHICH CONTAIN SOLID SODIUM HYDROXIDE TO WATER, BECAUSE HEAT IS RELEASED WHEN THE COMPOUND DISSOLVES. MAKE MUCH MOVEMENT OF THE SOLUTION, WITH AIR OR MECHANICAL METHODS, AS YOU ADD THE COMPOUND TO THE SURFACE OF THE SOLUTION. DO NOT ADD LARGE QUANTITIES OF THE COMPOUND TO ONE SMALL AREA OF THE TANK BECAUSE THE SOLUTION WILL BOIL.
WARNING
THE INSTRUCTIONS GIVEN BY THE SAFETY OFFICER MUST ALWAYS BE OBEYED.
