MBC 50-50

Principle Routes of Exposure

Ingestion, inhalation and skin absorption Signs and Symptoms of Overexposure: Methyl Bromide: Symptoms appear slowly and include: dizziness, blurred vision, lassitude, sensation of fatigue, staggering gait, slurred speech, nausea, vomiting, lack of appetite, and loss of muscle coordination. High concentrations can cause convulsions, very high concentrations cause lung damage. Prolonged skin and eye contact can cause burns. Chloropicrin: Chloropicrin is a powerful irritant with effects observed on all body surfaces. Liquid chloropicrin is corrosive to skin. It causes severe watering of the eyes, shortness of breath (pulmonary edema), dizziness, nausea and vomiting. Severe exposure may cause weak and irregular heartbeat, asthmatic attack and may be fatal. Skin wounds exposed to chloropicrin become septic.

Medical Conditions Generally Aggravated by Exposure

Dermatitis Respiratory disorders

Potential health effects

See Section XI for additional information. Eyes: Corrosive to the eyes. May cause chemical burns. Blurred vision Prolonged eye exposure may result in blindness. Skin: Corrosive to skin. May cause chemical burns. Ingestion: Toxic. May be harmful if swallowed. Inhalation: Highly toxic. May be fatal if inhaled. May cause severe mucous membrane and respiratory tract irritation, respiratory distress, irregular heartbeat, cardiac arrest and nervous system effects.

Potential chronic health

Can cause weak and irregular heartbeat. Target organs may include the liver, kidneys, lungs, stomach, heart and skeletal muscles. ACGIH has classified chloropicrin as an A4, Not Classifiable as a Human Carcinogen. Chronic overexposure may cause neurotoxic effects including peripheral nerve damage and central nervous system effects, respiratory effects and cardiac effects. ACGIH has classified methyl bromide as an A4, Not Classifiable as a Human Carcinogen. Methyl bromide has been classified as Group 3 by IARC. An IARC Group 3 material exhib its limited evidence for carcinogenicity in experimental animals and no human data. SECTION III - H AZ ARDS IDE NTI F I CATI ON Based on an epidemiology study, methyl bromide may be associated with an increase in prostate cancer risk in both private and commercial pesticide applicators. May cause genotoxic effects. Carcinogenicity: NTP: No ACGIH: No IARC: No OTHER: No OSHA: No
