SECTION VII - HANDLING AND STORAGE
Use appropriate personal protection equipment.
Handling:
Avoid eye, skin and clothing contact.
Do not breathe mist or vapor.
Cylinders should not be subjected to rough handling or mechanical
shock such as dropping, bumping, dragging, or sliding. Do not use
rope slings, hooks, tongs, or similar devices to unload cylinders.
Transport cylinders using hand truck, fork truck or other device to
which the cylinder can be firmly secured. Do not remove valve
protection bonnet and safety cap until immediately before use.
Replace safety cap and valve protection bonnet when cylinder is not in
use. When cylinder is empty close, valve, screw safety cap onto valve
outlet, and replace protection bonnet before returning to shipper.
Only a registrant is authorized to refill cylinders. Do not use cylinders
for any other purpose.
Store upright in a cool, dry, well-ventilated area under lock and key.
Storage:
Post as a pesticide storage area.
Store cylinders upright, secured to a rack or wall to prevent tipping.
Keep container tightly closed.
Methyl bromide has no odor at dangerous levels and is extremely
Other Precautions:
hazardous.
Do not contaminate water, food, or feed by storage or disposal.

Full face shield or safety glasses with brow and temple shields. Do
Eye/Face Protection:
NOT wear goggles.
Do not use gloves.
Skin Protection:
Loose-fitting or well ventilated long-sleeved shirt and pants. Shoes
and socks. Do NOT wear jewelry, gloves, tight clothing, rubber
protective clothing, or rubber boots when handling.
If the concentration of methyl bromide as measured by detector tube
Respiratory Protection:
exceeds 5 ppm at any time, all persons in fumigation area must wear
NIOSH/MSHA approved SCBA.
Consult the OSHA respiratory protection information located at
29CFR 1910.134 and the American National Standard Institute's
Practices of Respiratory Protection Z88.2.

SECTION XI - TOXICOLOGICAL INFORMATION
VALUE (LD50 OR LC50) ANIMAL ROUTES COMPONENTS
3,120 ppm/15 Minutes Rat Acute Inhalation Methyl Bromide
302 ppm/8H Rat Acute Inhalation Methyl Bromide
214 mg/kg Rat Acute Oral Methyl Bromide
Toxicological Information:
An inhalation LCLo of 60,000 ppm for 2 hours has been found in humans. Methyl bromide is a poison and
can cause respiratory distress, cardiac arrest and central nervous system effects. Overexposure may cause
neurotoxic effects from which recovery may be slow. Methyl bromide demonstrates genotoxicity in several
test systems at levels above the TLV.
In a two year inhalation cancer bioassay with rats at 3, 30 and 90 ppm no tumors were observed.
In a two generation inhalation reproduction study with rats at 3, 30 and 90 ppm the no observed effect level
was 3 ppm. At the higher doses organ weight variation was observed in some offspring.
In a 24 month chronic dietary study in rats, a no observable effect level (NOEL) for systemic toxicity of
microencapsulated methyl bromide was considered to be 50 ppm (equivalent to 2.20 mg/kg/day for males and
2.92 mg/kg/day for females). The low observable effect level (LOEL) was considered to be 250 ppm
(equivalent to 11.10 mg/kg/day for males and 15.12 mg/kg/day for females) based on reduced food
consumption, body weight gains and body weights noted during the first 12 to 18 months of the study.
Methyl bromide was not oncogenic upon dietary administration for two years.
