3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW:
CAUTION! May be harmful if swallowed, inhaled, or absorbed through the
skin. Do not breathe dust, get in eyes, on skin or clothing.
Keep granules away from children, dogs and other pets. Bait may be
attractive to dogs.
Do not contaminate water supplies.
POTENTIAL HEALTH EFFECTS
ROUTE(S) OF ENTRY: Typical routes of entry are skin or eye contact, ingestion of granules, and
inhalation of dusts.
SIGNS OF ACUTE OVEREXPOSURE: Based on animal toxicity information for metaldehyde, it
is anticipated that this material would be harmful upon ingestion and that direct contact may
elicit mild eye and skin irritation. Overexposure to metaldehyde may cause excessive
salivation, vomiting, nausea, acetonuria (odor of acetone on breath), convulsions, increased
body temperature, depression of medullary respiratory and vasomotor control centers. Coma.
May be fatal. [Note: Because of the low amounts of metaldehyde in the product, it is unlikely
the victim can be exposed to sufficient quantities of metaldehyde to have coma or death
induced.]
SIGNS OF CHRONIC OVEREXPOSURE: Same as for acute overexposure.
OTHER POTENTIAL EFFECTS: Acetaldehyde, a decomposition product of Metaldehyde, has been
listed as carcinogenic in the IARC monographs and by the NTP. Respirable crystalline silica
is listed as being carcinogenic by both IARC and NTP. Both are present at less than 0.01% in
the product. None of the components found in appreciable quantities has been found to be
carcinogenic by IARC, NTP, or OSHA.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Overexposure may aggravate
preexisting conditions associated with the kidney, liver, and brain.
4. FIRST AID MEASURES
EYES: Immediately flush the eyes with copious amounts of clear, cool running water for a minimum of
15 minutes. Hold the eyelids apart during the flushing to ensure rinsing of the entire surface of
the eyes and lids with water. Contact a physician immediately if irritation develops or persists.

4. FIRST AID MEASURES, cont'd
INHALATION: Remove victim to fresh air. If breathing has ceased, clear the victim's airway and start
mouth-to-mouth artificial respiration. If breathing is difficult, give oxygen. Contact a physician
immediately.
INGESTION: If swallowed, immediately give 3-4 glasses of water. DO NOT induce vomiting. If
vomiting occurs, give fluids again. Get immediate medical attention. Have physician determine
if patient' condition allows induction of vomiting or evacuation of stomach. Do not give
s
anything by mouth to an unconscious or convulsing person.
SKIN: Immediately wash contaminated area with soap and warm water. Remove contaminated clothing.
Wash clothing before reuse. If skin irritation develops, contact a physician immediately.
NOTE TO PHYSICIANS: According to Hazardous Substance Database (HSDB), gastric lavage
should be considered if potentially life-threatening levels of Metaldehyde have been ingested,
if the procedure can be performed within one hour of ingestion. Administration of Diazepam
or Clonidine 20 minutes after ingestion of 1000 mg/kg of Metaldehyde by mice delayed the
onset of symptoms and reduced mortality. This is equivalent to 0.6 lb of product ingested for a
10 kg child. Therefore, Diazepam and Clonidine may be appropriate antidotes to reduce the
symptomatology of Metaldehyde ingestion.
For acute inhalation overexposure, the patient should be monitored as respiratory failure may
occur 24 to 48 hours after exposure.
Contact your local or state Poison Control Center for more information.

5. FIRE FIGHTING MEASURES, cont'd
FIRE FIGHTING INSTRUCTIONS: Wear full protective clothing, including self-contained breathing
apparatus. Stay upwind of fire.
6. ACCIDENTAL RELEASE MEASURES
GENERAL: Use adequate ventilation and air-supplied respirators, as well as impervious clothing and
safety goggles. Keep bystanders upwind and away from the spill.
LARGE OR SMALL SPILL: Sweep or vacuum the spilled product into a closed container for reuse
according to the label or for disposal as a hazardous waste.
7. HANDLING AND STORAGE
HANDLING: Wear personal protective equipment listed below (Section 8). Keep away from pets,
children, and unauthorized users. Avoid contact with dust.
STORAGE: Store product in original labeled container in a cool, dry, locked place out of the reach of
children. Keep container tightly closed when not in use. Do not store in direct sunlight. Do not
contaminate water, food, or feed by storage or application.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS: No engineering controls are necessary under normal use conditions.
For manufacturing, sufficient ventilation should be used to ensure keeping the exposures to dust
below the TLV's.
RESPIRATORY PROTECTION: In processes where dusts or airborne particulates may be generated,
a Dust/Mist filtering respirator (MSHA/NIOSH approval number prefix N95 or greater) or
MSHA/NIOSH approved respirator with dust cartridges or equivalent is required in the absence
of effective environmental controls.
SKIN PROTECTION: Applicators and other handlers must wear long-sleeved shirt and long pants;
waterproof gloves; shoes plus socks.
EYE PROTECTION: Safety glasses or goggles are required when working with chemicals.
