First-aid measures
Get immediately medical attention.
After inhalating : Immediately remove from exposure area to fresh air. If respiration has stopped perform artificial respiration. Keep person warm and at rest. Treat symptomatically and supportively. Get immediately medical attention.
After skin contact : Immediately remove contaminated clothing and shoes. Wash contaminated area with soap or mild detergent and large amount of water until no evidence of chemicals remains. Lesions can be scrubbed with a 20 % solution of sodium hyposulfite or treated with a calcium-disodium EDTA ointments. Freshly prepared and promptly applied 10 % ascorbic acid solution may speed healing of ulcers (Gosselin Clinical toxicology of Commercial Products , 5th Ed). As will 1 % solution of aluminium acetate wet dressing (Arena, Poisoning 4th Ed.).
After eye contact : Wash eyes immediately with large amounts of water, occasionally lifting upper and lower lids, until no evidence of chemical remains (at least 15-20 minutes). Continue irrigating with normal saline until pH has returned to normal (30-60 minutes) cover with sterile bandages. Get immediately medical attention.
After ingestion : If the person is conscious and not convulsing, induce vomiting by giving syrup of ipecac (keeping the head below hips level to prevent aspiration), followed by water. Repeat in 20 minutes if not effective initially. For patients with depressed respiration or if vomiting has not worked out, perform gastric lavage cautiously (Dreisbach, Handbook of Poisoning, 12th Ed.). Treat symptomatically and supportively. Gastric lavage should be performed by qualified medical personnel. Get immediately medical attention.
NOTE TO PHYSICIAN
ANTIDOTE : The following antidote has been recommended. However, the decision as to whether the severity of poisoning requires administration of any antidote and actual dose required should be made by qualified medical personnel.
CHROMIUM POISONING : Use of dimercaprol has been suggested on the basis of findings in animals. Give 3 mg/kg (or 0.3 ml/10 kg) every 4 hours, intramuscularly for the first 2 days and then 2 mg/kg every 12 hours for a total of 10 days (Dreisbach Handbook of Poisoning, 12th Ed.). Antidote should be administered by qualified medical personnel.
POISONING FROM ZINC SALTS : Give calcium disodium edetate 15-25 mg/kg (0.08-0.125 ml of 20 % solution per Kg of body weight) in 250-500 ml of 5 % dextrose intravenously over a 1 to 2 hour period twice daily. The maximum dose should not exceed 50 mg/kg/day. The drug should be given in 5-day courses with a rest period of at least 2 days between courses. After the first course, subsequent courses should not exceed 50 mg/kg/day. Daily urine analyses should be done during the treatment period. The dosage should be reduced if any unusual urinary findings appear. For intramuscular administration, give 12.5 mg/kg body weight every 4-6 hours. Dilute each dose with an equal volume of 1 % procaine. Dose limitation is the same as that given above. (Dreisbach, Handbook of Poisoning, 12th Ed.). Antidote should be administered by qualified medical personnel.
Fire-fighting measures
Suitable extinguishing media : CO2, dry chemical, regular foam.
Not recommended : Water spray (chromate slightly soluble in water). Do not let this material and its solution contaminate the Environment.
Specific hazards : Negligible hazard when exposed to flames. Keep away from dust. Keep away from reducers (ex-hydrazine, wood, sulphur, paper, aluminium).
Special personal protection equipment : Wear an air respirator beyond dust limits, gloves and appropriate clothing and equipment to prevent a prolonged skin contact with substance.
Conduct of fire fighting : Avoid dusting. Keep away unprotected people. Move container from fire area if possible without risk. Do not scatter spilled material with high-pressure water streams. Dike and contain fire-control water for later disposal. (chromate slightly soluble in water). Contaminated wastes have to be collected by a licensed contractor. Do not let contaminated water contaminate the environment
Additional information: The fire water, waste contaminated containers and Fire residues containing zinc tetraoxi-chromate must be removed by a licensed contractor for garbage.
Accidental release measures
Personal protective measures : Avoid dusting. Wear appropriate dust mask (FFP3 [EN 149]) or better appropriate respirator, glasses and gloves and appropriate clothing equipment to prevent from a prolonged skin contact with this substance. Keep unnecessary people away.
Environmental protection conduct : Do not get rid of waste waters, neither in discharge, nor in sewers, but according to local regulations.
Occupational spill : Avoid dusting. Sweep up in suitable clean, dry container or absorb material avoiding dusting. Do not flush spilled materials into sewer. Keep unnecessary people away.
Soil spill : Dig a holding area such as pit, pond or lagoon to contain spilled material. Use protective cover such as plastic sheet to prevent dissolving in fire-fighting water or rain. Dusting is prohibited.
Water spill : For total elimination. Detoxication of Cr6+ is recommended (Cr6+ in waste water is prohibited according to local regulations). For this purpose add FeSO4 for the chromium reduction and then proceed to Cr3+ flocculation by neutralisation (pH 8-9) with sodium carbonate, lime. Use mechanical dredges or lifts to extract immobilised masses of pollution and precipitates.
Air spill : A hazardous concentration of particles in suspension in the air can quickly be reached by dispersion. Keep unnecessary and unprotected people away. Let the particles suspension fall down and go into the place with appropriate individual protection equipment : respirator (or dust mask) and protective (impervious) clothing. Prevent any contact with food and animal feeding stuff.
Handling and storage
EC : The directive 90/394/EC dealing with the prevention of exposition risks to carcinogenic agents in workhouses applies to this substance (see Chapter 15). The directive 98/24/EC deals with the workers health and security protection against chemical risks in workhouses.
Handling : Avoid dust breathing and use adequate ventilation. Protection is required to keep exposure below permissible limit (see Chapter 8 and 15). Refer to Chapter 8 to know the protection means you have to wear.
Protection against fire and explosion : The product is non-flammable. It may reduce the ignition temperature of flammable substances.
Storage : Store in roofed place at room temperature. Keep containers tightly sealed. Do not store with or close to food and animals feeding stuff (see Chapter 15).
Material/chemical incompatibility : Do not store close to reducers (ex-hydrazine, aluminium powder...)
Technical incompatibility: Chromate can be reduced (slight change of the strontium chromate colour which becomes greenish – reduction of Cr6+ in Cr3+ –). This colour change is more sensitive with alcohols from 50°C and up. This reaction does not occur at room temperature.
