Description of necessary first aid measures
If inhaled: If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contact: Wash off with soap and plenty of water. Consult a physician.

If swallowed: If swallowed do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
Most important symptoms and effects, both acute and delayed: /
Indication of immediate medical attention and special treatment needed : For acute or short term repeated  exposures  to strong acids:  Airway problems may arise  from  laryngeal edema and inhalation   exposure.   Treat   with   100%   oxygen   initially.   Respiratory   distress   may   require cricothyroidotomy    if    endotracheal    intubation    is    contraindicated    by    excessive    swelling. INGESTION:   Immediate   dilution   (milk   or   water)   within   30   minutes   post   ingestion   is recommended. DO NOT attempt to neutralise the acid since exothermic reaction may extend the corrosive  injury.  SKIN:  Skin  lesions  require  copious  saline  irrigation.  Treat  chemical  burns  as thermal burns with non-adherent gauze and wrapping. EYE: Eye injuries require retraction of the eyelids to ensure thorough irrigation of the conjuctival cul-de-sacs. Irrigation should last at least 20-30 minutes. DO NOT use neutralising agents or any other additives.     Several litres of saline
are required.
Suitable extinguishing media: dry chemical, carbon dioxide, sands.
Special  hazards  arising  from  the  chemical:  Combustible.  Slight  fire  hazard  when  exposed  to heat  or  flame.  Heating  may  cause  expansion  or  decomposition  leading  to  violent  rupture  of containers. May emit acrid smoke and corrosive fumes.
Special  protective  actions  for  fire-fighters:  Wear  full  body  protective  clothing  with  breathing apparatus. Prevent, by any means available, spillage from entering drains or water course. Use fire fighting procedures suitable for surrounding area. Do not approach containers suspected to be hot. Cool fire exposed containers with water spray from a protected location. If safe to do so, remove
containers from path of fire.
Personal precautions, protective equipment and emergency procedures: Remove all ignition sources.  Clean  up  all  spills  immediately.  Avoid  contact  with  skin  and  eyes.  Control  personal contact with the substance, by using protective equipment.
Environmental  precautions:  Prevent,  by  any  means  available, spillage  from  entering  drains  or water course.
Methods  and  materials  for  containment  and  cleaning  up:  Contain  spill  with  sand,  earth  or vermiculite.     Collect     recoverable     product     into     labelled     containers     for     recycling. Neutralise/decontaminate  residue. Collect solid  residues and  seal  in  labelled drums for  disposal.
Wash area and prevent runoff into drains.
Precautions for safe handling: Avoid all personal contact, including inhalation. Wear protective clothing  when  risk  of  exposure  occurs.  Use  in  a  well-ventilated  area.  WARNING:  To  avoid violent reaction, ALWAYS add material to water and NEVER water to material. Avoid smoking, naked lights or ignition sources. Avoid contact with incompatible materials. When handling, DO NOT eat, drink or smoke. Keep containers securely sealed when not in use.
Avoid physical damage to containers.
Conditions for safe storage, including any incompatibilities: Store in original containers. Keep containers   securely   sealed.   Store   in   a   cool,   dry,   well-ventilated   area.   Store   away   from incompatible materials and foodstuff containers. Protect containers against physical damage and check   regularly   for   leaks.   Observe   manufacturer's   storage   and   handling   recommendations contained within this MSDS.
Control parameters:
Appropriate  engineering  controls:  Local  exhaust  ventilation  is  required  where  solids  are handled  as  powders  or  crystals.  If  in  spite  of  local  exhaust  an  adverse  concentration  of  the substance in air could occur, respiratory protection should be considered.
Individual protection measures
Eye/face protection: Chemical goggles. Full face shield may be required for supplementary but never  for  primary  protection  of  eyes;  these  afford  face  protection.  Contact  lenses  may  pose  a special hazard; soft contact lenses may absorb and concentrate irritants.
Skin  protection:  Wear  chemical  protective  gloves,  e.g.  PVC.  Wear  safety  footwear  or  safety gumboots,  e.g.  Rubber.  The  material  may  produce  skin  sensitisation  in  predisposed  individuals. Care must be taken, when removing gloves and other protective equipment, to avoid all possible skin  contact.  Gloves  must  only  be  worn  on  clean  hands.  After  using  gloves,  hands  should  be washed and dried thoroughly.
Respiratory protection: Selection of the Class and Type of respirator will depend upon the level of breathing zone contaminant and the chemical nature of the contaminant.
