2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Will cause damage to the mucous membranes. Eye
High concentrations of vapours will cause irritation. Liquid will cause burns. Contamination of eyes can result in permanent injury. Skin
Causes burns. Contact with skin will result in severe irritation. Inhaled
The vapour is an irritant to the mucous membranes and respiratory tract. May cause bronchitis, pneumonia and pulmonary oedema. Casualty may appear sweaty pale or slightly blue, have rapid breathing and cough up frothy sputum which may be pink or flecked with blood. 2.2 Health Effects - Chronic
No data available
2.3 First Aid
Swallowed
Drink 2 - 3 glasses of water and transport to hospital immediately.
Eye
Irrigate with clean water for at least 15 minutes, retract eyelids often. Seek medical attention immediately.
Skin
Flood exposed skin with water. Remove contaminated clothing then wash with soap and water thoroughly. Seek medical advice if effects persist.
Inhaled
Move patient to fresh air. If breathing stops, start artificial respiration. Congestion of the lungs may occur any time after inhalation of fumes. If a conscious victim develops difficulty with breathing, and particularly if congestion of the lungs is suspected, they should be placed in the sitting up position and constantly observed for any change in behaviour, particularly the pulse or respiration, until medical help arrives. Congestion of the lungs is a serious complication and the casualty should be transferred to hospital as soon as possible.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
DO NOT use gastric lavage or emesis. Dilute the acid by drinking quantities of water or milk. If vomiting is persistent, administer fluids repeatedly.
2.6 Toxicity Data
Oral LD50 = 3310 mg/kg (Rat) Dermal LD50 = 1060 mg/kg (Rabbit) Inhalation LD50 = 5620 ppm/1 hr (Mouse)
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
The following exposure standards are recommended, however attempts should be made to reduce exposure to zero : TWA = 10 ppm (25 mg/m3) - Worksafe STEL = 15 ppm (37 mg/m3) - Worksafe
3.2 Engineering Controls
Use local exhaust ventilation to maintain exposure below standards.
3.3 Personal Protection
Ensure an eye bath and safety shower are available and ready for use. Workers should wear rubber footwear, overalls, PVC gloves and goggles. For any handling operation that may involve exposure by inhalation of vapour or aerosol spray, then approved respiratory protection should be worn. Remove all contaminated clothing after use and launder before reuse. Wash hands thoroughly before eating, drinking, smoking or using the toilet.
3.4 Flammability
Material is flammable/combustible. SAFE HANDLING INFORMATION
4.1 Storage / Transport

Safety Phrases S1/2 Keep locked up and out of the reach of children. S23:ACACID Do not breathe fumes/vapour. S26 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S45 In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible).
4.3 Spills and Disposal
Spills
Remove all sources of ignition. NO SMOKING. Clean up personnel should wear full protective clothing including rubber boots, gloves and goggles or face shield. Keep people away and upwind. If contamination of drains, streams, watercourses etc, is unavoidable warn the Local Water Authority immediately.
For small spills wash to drains with copious amounts of water. For large spills contain by surrounding and covering with inert absorbent materials eg sand, earth, vermiculite etc. Sweep up carefully and shovel into marked open-head containers. Spread more inert material over the entire spill area, sweep up and shovel sweepings into the marked container.
Disposal
Wash contaminated area with detergent and water. Dispose of waste material in accordance with all Local, State and Federal regulations at an approved waste disposal site.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Spontaneous ignition temperature 430 deg C. Heating will cause pressure rise with risk of bursting containers. Incompatible with chromic acid, nitric acid, hydroxyl compounds, ethylene glycol, perchloric acid, peroxides, permanganates.
Extinguishing Media
Use water or carbon dioxide, dry powder or carbon dioxide type extinguishers. Fire-exposed containers should be cooled with water spray. Use media-equipment appropriate to surrounding fire conditions. Fire-fighters should wear full protective equipment including self-contained breathing apparatus. 5 OTHER INFORMATION
Other Information
Disposal in drains is forbidden (risk of explosion, corrosion, pollution). If unavoidable only after neutralisation and dilution.
