IV FIRE AND EXPLOSION H AZARDS DATA

Flash Point: N/E or N /A Method U sed: Non-flam ma ble
Explosive Lim its: Lower: N/A Upper: N/A

Extingu ishing Media: Use suitable extinguishing media for surrounding material and type of fire.
Special Fire Fighting Procedures: Firefighters m ust w ear fu ll face, self-con tained breathing apparatus and full pro tective clothing to
prev ent co ntact w ith skin and eyes. Fum es from fire are h azard ous. Isolate ru noff to pre ven t environme ntal pollution.

Unusual Fire and Explosion Hazards: When heated to decomposition, aluminum telluride emits toxic fumes of tellurium.

V HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of aluminum telluride have not been
thoroughly investigated and recorded.

Aluminum compounds have many commercial uses and are commonly found in industry. Many of these materials are active
chemic ally an d thu s exh ibit dan gero us tox ic and reactiv e pro perties. Inha lation o f fine alum inum oxid e particles is associated with
Shaver's disease.

Elemental tellurium has relatively low toxicity. It is converted in the body to dimethyl telluride which imparts a garlic-like
odor to the breath and sweat. Heavy exposures may, in addition, result in headache, drowsiness, metallic taste, loss of appetite,
nausea, tremors, convu lsions, and respiratory arrest (Sax, Dangerou s Properties of Industrial Materials, eighth edition).
Acute E ffects:

Inhalation: Ma y cau se irritation to the respiratory system , a dry mo uth, g arlic od or to b reath, sweat and urine .
Ingestion: Ma y cau se a dry m outh , supp ression of sw eat, garlic odor to b reath and urine.
Skin : May cause irritation and itching.
Eye: May cause irritation.

Chro nic Effects:

Inhalation: May cause an orexia, na usea, dep ression, som nolence and pulm onary fibrosis.
Ingestion: May cause anorexia, nausea, depression and somnolence.
Skin : May cause dermatitis.
Eye: No chronic health effects recorded.

Target Organs: May affect the skin and central nervous system.

Carcino genicity: NTP: No IARC: No OSHA Regulated: No
Medical Conditions Generally Aggravated by Exposure: Pre-existing skin disorde rs.

Routes of Entry: Inhalation, skin, eyes, ingestion

EMERG ENCY AND FIRST AID PROCEDURES:

INHALATION: Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 glasses of milk or water and induce vomiting, seek medical attention immediately. Never induce vomiting
or give anything by mouth to an unconscious person.
SK IN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water for 15 minutes, seek
me dical attention if sym ptom s persist.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms
persist.

VII SPILL OR LEAK PROC EDURES

Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective equipment specified in
Section VIII. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA ) air filter
and place in a closed container fo r proper d isposal. Tak e care not to raise du st.

VIII SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type): Wear a NIO SH-app roved du st respirator.
Ventilation: Use local exhaust to maintain concentration at or below PEL, TLV. General exhaust is not recommended.

Protective Gloves: Rubber gloves
Eye Protection: Safety Glasses

Other Protective Equipment: Wear protective clothing to prevent contamination.

IX SPECIAL PRECAUTIONS

Precautions to be Taken in Handling and Storing: Store in a co ol, dry area, W ash thorough ly after handling . Store in tightly
sealed container.

Wo rk Practices: Imp lem ent en gineering and wo rk practice controls to re duc e and ma intain c onc entration o f exp osure at low levels.
Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and
smoking. do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench
shower and facilities for washing.

The above information is accurate to the best of our knowledge. However, since, data, safety standards, and government
regulation are subject to change, and the conditions of handling and use or misuse are beyond our control, ESPI makes no warranty,
neither expressed nor implied, with respect to the completeness or continuing accuracy of the information contained herein, and
disclaims all liability for reliance thereon. Users should satisfy themselves that they have all current data relevant to their particular
