Potential Health Effects
----------------------------------
Due to low water solubility and relatively high lipid solubility, DMP
is able to accumulate in body tissues. As a result, chronic exposure tends to
be more important than acute exposure.
Inhalation:
Toxic.
Inhalation of vapors irritates the respiratory tract. Symptoms may include
coughing, shortness of breath and chest pain. At room temperature the
substance has such a low vapor pressure that inhalation of the vapor is
unlikely.
Ingestion:
Swallowing can cause burning sensation of
lips, tongue, mouth; vomiting and diarrhea may occur. Central nervous system
effects, including coma, are possible.
Skin Contact:
May cause
irritation with redness and pain.
Eye Contact:
Causes
irritation, redness, and pain.
Chronic Exposure:
May accumulate
in body tissues. May affect central nervous system.
Aggravation of
Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:
Induce vomiting immediately as directed
by medical personnel. Never give anything by mouth to an unconscious person.
Get medical attention.
Skin Contact:
Immediately flush skin
with plenty of water for at least 15 minutes. Remove contaminated clothing and
shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get
medical attention if irritation develops.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes,
lifting lower and upper eyelids occasionally. Get medical attention
immediately.
5. Fire Fighting Measures
Fire:
Flash point: 146C (295F) CC
Autoignition
temperature: 490C (914F)
Flammable limits in air % by volume:
lel:
0.9
Slight fire hazard when exposed to heat or flame.
Explosion:
Above the flash point, explosive vapor-air mixtures may be formed.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol
foam, or carbon dioxide. Water spray may be used to keep fire exposed
containers cool. Water or foam may cause frothing.
Special
Information:
In the event of a fire, wear full protective clothing and
NIOSH-approved self-contained breathing apparatus with full facepiece operated
in the pressure demand or other positive pressure mode.
6. Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill.
Wear appropriate personal protective equipment as specified in Section 8.
Isolate hazard area. Keep unnecessary and unprotected personnel from entering.
Contain and recover liquid when possible. Collect liquid in an appropriate
container or absorb with an inert material (e. g., vermiculite, dry sand,
earth), and place in a chemical waste container. Do not use combustible
materials, such as saw dust. Do not flush to sewer! US Regulations (CERCLA)
require reporting spills and releases to soil, water and air in excess of
reportable quantities. The toll free number for the US Coast Guard National
Response Center is (800) 424-8802.
7. Handling and Storage
Containers of this material may be hazardous when empty since they
retain product residues (vapors, liquid); observe all warnings and precautions
listed for the product. Keep in a tightly closed container, stored in a cool,
dry, ventilated area. Protect against physical damage. Isolate from
incompatible substances.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure
Limit (PEL): 5 mg/m3 (TWA)
-ACGIH Threshold Limit Value (TLV): 5 mg/m3
(TWA)
Ventilation System:
A system of local and/or general
exhaust is recommended to keep employee exposures below the Airborne Exposure
Limits. Local exhaust ventilation is generally preferred because it can
control the emissions of the contaminant at its source, preventing dispersion
of it into the general work area. Please refer to the ACGIH document,
Industrial Ventilation, A Manual of Recommended Practices, most recent
edition, for details.
Personal Respirators (NIOSH Approved):
If
the exposure limit is exceeded, a half-face respirator with an organic vapor
cartridge and particulate filter (NIOSH type P95 or R95 filter) may be worn
for up to ten times the exposure limit or the maximum use concentration
specified by the appropriate regulatory agency or respirator supplier,
whichever is lowest. A full-face piece respirator with an organic vapor
cartridge and particulate filter (NIOSH P100 or R100 filter) may be worn up to
50 times the exposure limit, or the maximum use concentration specified by the
appropriate regulatory agency or respirator supplier, whichever is lowest.
Please note that N series filters are not recommended for this material. For
emergencies or instances where the exposure levels are not known, use a
full-face piece positive-pressure, air-supplied respirator. WARNING:
Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres. This compound possibly exists in both particulate and vapor
phase. A gas/vapor cartridge should be used in addition to the particulate
filter (NIOSH type P95 or better filter). If the vapor concentration alone
exceeds the exposure limits, use a supplied air respirator, because warning
properties are unknown for these compounds. Breathing air quality must meet
the requirements of the OSHA respiratory protection standard (29CFR1910.134).
Skin Protection:
Wear impervious protective clothing, including
boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin
contact.
Eye Protection:
Use chemical safety goggles and/or a
full face shield where splashing is possible. Maintain eye wash fountain and
quick-drench facilities in work area.
