First aid

General first aid measures. Get medical advice if you feel unwell

If inhaled
IMMEDIATELY leave the contaminated area, take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used, if not available, use a level of protection greater than or equal to that advised under Protective Clothing.
Skin contact
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
Eye contact
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
If swallowed
DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital.

Handling, storage and disposal

Summaries only, follow the supplier SDS for your grade

Safe handling

General: STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!

Inhalation: Use ventilation, local exhaust or breathing protection.

Skin: Protective gloves. Protective clothing.

Eyes: Wear safety spectacles, face shield or eye protection in combination with breathing protection.

Ingestion: Do not eat, drink, or smoke during work.

Storage

Separated from food and feedstuffs. See Chemical Dangers. Cooled. Keep in the dark. Ventilation along the floor.

Disposal

The following scheme is proposed for treating effluents from the production of chloropicrin. These wastewaters contain Ca(ClO)2 approx 2000 mg/l, chloropicrin approx 80 mg/L, and picric acid approx 80 mg/L. The Ca(ClO)2 is first removed by reduction with FeSO4 at 90-95 deg, and pH of 11-11.5. Complete removal is achieved in 3 hours. The nitro compounds are then reduced to MeNH2 and triaminophenol by heating the effluent from the first stage with FeSO4 and Fe turnings at 90-95 deg. Reduction of the nitro compounds is approx 81% complete, the residue containing compounds are not readily reduced. The MeNH2 vapor is oxidized to MeOH in a reactor containing a soln of NaNO2 and HCl at 5-6 deg. The reaction time is 2-2.5 hours. The MeOH and triaminophenol are then oxidized with Ca(ClO)2, and the final treated effluent is clearified before discharge.

Exposure limits and toxicity

Short-term exposure: Lachrymation. The substance is severely irritating to the eyes, skin and respiratory tract. Inhalation of the vapour may cause lung oedema. Exposure above the OEL could cause death. The effects may be delayed. Medical observation is indicated.
