Fire Hazard
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:
Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. For UN3508, be aware of possible short circuiting as this product is transported in a charged state. (ERG, 2016)

Health Hazard
Exposure Routes: inhalation, skin and/or eye contact
Symptoms: Irritation eyes, nose, throat, respiratory system; lacrimation (discharge of tears); cough; wheezing; [potential occupational carcinogen]
Target Organs: Eyes, respiratory system (NIOSH, 2016)

Reactivity Profile
FORMALDEHYDE (ENVIRONMENTALLY HAZARDOUS SUBSTANCES, SOLID, N.O.S.) may react violently with strong oxidizing agents (hydrogen peroxide, performic acid, perchloric acid in the presence of aniline, potassium permanganate, nitromethane). May react with bases (sodium hydroxide, potassium hydroxide, ammonia), and with nitrogen dioxide (explosive reaction around 180°C). May react with hydrochloric acid to form highly toxic bis(chloromethyl) ether. Polymerization reaction with phenol may develop sudden destructive pressure [Bretherick, 5th ed., 1995, p.168]. May generate flammable and/or toxic gases in combination with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. May generate toxic formaldehyde gas when heated. Can react with air to give first peroxo acids, and ultimately formic acid. These reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). Incompatible with liquid oxygen.

The

information in CAMEO Chemicals comes from a variety of
data sources.
Isolation and Evacuation
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:
As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above.
FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Firefighting
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:
SMALL FIRE: Dry chemical, CO2, water spray or regular foam.
LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal.
FIRE INVOLVING TANKS: Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)

Non-Fire Response
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:
Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent dust cloud. Avoid inhalation of asbestos dust.
SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.
SMALL SPILL: Pick up with sand or other non-combustible absorbent material and place into containers for later disposal.
LARGE SPILL: Dike far ahead of liquid spill for later disposal. Cover powder spill with plastic sheet or tarp to minimize spreading. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2016)

Protective Clothing
Skin: No recommendation is made specifying the need for personal protective equipment for the body.
Eyes: Wear appropriate eye protection to prevent eye contact.
Wash skin: No recommendation is made specifying the need for washing the substance from the skin (either immediately or at the end of the work shift).
Remove: No recommendation is made specifying the need for removing clothing that becomes wet or contaminated.
Change: No recommendation is made specifying the need for the worker to change clothing after the work shift. (NIOSH, 2016)

Testing Details
The fabric permeation data was generated for DuPont by independent
testing laboratories using ASTM F739, EN369, EN 374-3, EN ISO 6529
(method A and B) or ASTM D6978 test methods.
Normalized breakthrough times
(the time at which the permeation rate is equal to 0.1 µg/cm2/min)
reported in minutes.
All liquid chemicals have been tested between approximately 20°C and
27°C unless otherwise stated.
A different temperature may have significant influence on the
breakthrough time; permeation rates typically increase with
temperature.
All chemicals have
been tested at a concentration of greater than 95% unless otherwise
stated.
Unless otherwise stated, permeation was measured for single chemicals.
The permeation characteristics of mixtures can deviate considerably
from the permeation behavior of the individual chemicals.
Chemical warfare agents (Lewisite, Sarin, Soman, Sulfur
Mustard, Tabun and VX Nerve Agent) have been tested at 22°C and 50%
relative humidity per military standard MIL-STD-282.
