NONESafety Requirements
WARNING
IT IS THE RESPONSIBILITY OF THE OPERATOR TO OBTAIN AND OBSERVE THE MANUFACTURERS MATERIAL SAFETY DATA SHEETS FOR CONSUMABLE MATERIALS 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
EVERY POSSIBLE CARE MUST BE TAKEN TO AVOID THE SOLUTION COMING INTO CONTACT WITH THE EYES OR BARE SKIN. PROTECTIVE CLOTHING INCLUDING RUBBER GLOVES AND GOGGLES MUST BE PROVIDED FOR THE OPERATORS WHEN PREPARING AND USING THE ACID SOLUTION. RUBBER GLOVES SHOULD BE CHECKED REGULARLY FOR PIN HOLES AND REPLACED IF NECESSARY.
WARNING
SAFETY NOTICES MUST BE PLACED IN A CONSPICUOUS PLACE.
WARNING
EYE-WASH BOTTLES AND HF BURN JELLY MUST BE PROVIDED AS CLOSE AS POSSIBLE TO THE PLACE OF WORK.
WARNING
IF SKIN BECOMES CONTAMINATED WITH THE SOLUTION IT MUST BE RINSED WITH COPIOUS AMOUNTS OF CLEAN RUNNING WATER.
WARNING
ALL BURNS, HOWEVER SLIGHT, SHOULD BE TREATED AT THE NEAREST SURGERY OR FIRST AID POST.
WARNING
THE SURGERY MUST BE TOLD WHICH SOLUTION (THE ACIDS INVOLVED) HAS CAUSED THE BURN.
WARNING
THE OPERATORS MUST ALWAYS WEAR THE PROTECTIVE CLOTHING SUPPLIED, WHICH INCLUDES RUBBER GLOVES AND EYE PROTECTION
WARNING
IF SODIUM HYDROXIDE SOLUTION GETS INTO THE EYES FULLY FLUSH THEM, WITH CLEAN WATER, THEN GET MEDICAL TREATMENT IMMEDIATELY.
WARNING
A SUPPLY OF BUFFERED PHOSPHATE SOLUTION MUST ALWAYS BE EASILY AVAILABLE, TO APPLY TO BURNS.
WARNING
CARE MUST BE TAKEN WHEN YOU ADD COMPOUNDS WHICH CONTAIN SOLID SODIUM HYDROXIDE TO WATER, BECAUSE HEAT IS GIVEN OUT 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.
Procedure
Analyze the solution by pipeting 5 ml of the cooled solution, as prepared in the SPM TASK 70-33-89-100-501, into a 400 ml beaker and dilute with approximately 75 ml of distilled water.
Add five drops of CoMat 01-011 INDICATOR and titrate with 1N CoMat 01-008 SODIUM HYDROXIDE NaOH (CAUSTIC SODA), SOLID solution to the end point shown by color change to pink.
ml of 1N NaOH solution x 12.6 = g/l HN03.
