Please no hand written. please type the answer . Thank you!!!

Answer 1

a) Potential acute health effects :

i) may cause irreversible eye injury.vapor or mist may cause irritation or severe burns. Direct contact with eye is corrosive and cause severe burns.

ii) contact with skin can cause severe burns and ulceration. severity depends upon concentration of solution and duration of exposure.

iii) Ingestion may cause irritation and permanent tissue destruction of oesophagus and digestive tract.

iv) Inhalation may cause sore throat, coughing ,shortness of breath and causes corrosive action to mucous membrane.

b) Chronic health effect : Prolonged or repeated skin contact may cause dermatitis. Repeated exposure may cause erosion of teeth. Repeated exposure to low concentrations of HCl vapor or mist may cause bleeding of nose and gums. Chronic bronchitis and gastritis have also been reported.

c) First aid measures of ingestion:If swallowed, do NOT induce vomiting. Get medical aid immediately. If victim is fully conscious, give a cupful of water. Never give anything by mouth to an unconscious person. Never use Sodium bicarbonate to neutralise the acid.

d) Not flammable by its own but it can generate hydrogen gas by reaction with alkali metals which is flammable.

e) Reacts with sulphides ,carbides ,borides and phosphides to give flammable gas.

f)  Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately. Isolate area and deny entry. Provide ventilation. Spill may be carefully neutralized with lime (calcium oxide, CaO). A vapor suppressing foam may be used to reduce vapors. Approach spill from upwind.

g) Personal protection when working with the chemicals

Eyes: Wear chemical splash goggles and face shield.
Skin: Wear appropriate gloves to prevent skin exposure.
Clothing: Wear appropriate protective clothing to prevent skin exposure

Wear proper mask and adequate ventillation
