IV FIRE AND EXPLOSION H AZARDS DATA

Flash Point: N/A
Explosive Lim its: Lower: N/A Upper: N/A

Extingu ishing Media: Use extinguishing media suitable for surrounding materials and type of fire.
Special Firefighting Procedures: Firefighters m ust w ear fu ll face, self-con tained breathing apparatus with full pro tective clothing to
prevent contac t with skin an d eyes. Fu mes from fire are hazardou s.
Unusual Fire and Explosion Hazard: Do not use water to extinguish fires around operations involving molten metal due to the
potential for steam ex plosions.


V HEALTH HAZARD INFORMATION

Effects of Exposure:

Acute E ffects: In general, the metal dust and fumes of those elements listed in Section II can cause irritation to the skin, eyes, nose,
throat, lungs and mucous membranes. Symptoms may include cough, metallic taste in mouth, fever, fatigue and nausea. The
bery llium fraction of this pro duc t is insoluble an d do es no t cause acute bery llium disease. Ex cessive inhalation of co ppe r or co balt
can cause respiratory irritation, cough, bronchitis, chills, 鈥渕etal fume fever,鈥? decreased pulmonary function, and asthma-like
symptoms. Contact with cobalt or copper may cause allergic skin reactions. The beryllium in this product does not pose a potential
for an allergic dermal response.
Chro nic Effects:

In general, the metal dust and fumes of those elements listed in Section II can cause respiratory disease with symptoms which
include co ugh , chest pain, shortness o f brea th, weight loss, weakness and fatigue. Ex cessive exp osure to airborne particulate
containing beryllium or cob alt may cause long-term health effects including loss of lung function, fibrosis, or subsequent secondary
effects on the heart with eventual permanent impairment. Overexposure to airborne beryllium particulate may cause a serious lung
disease, in certain sensitive indiv iduals, called chronic beryllium d isease (chro nic berylliosis). Chronic berylliosis is a cond ition in
which the tissues of the lungs become inflamed, restricting the exchange of oxygen between the lungs and the bloodstream.

Medical Conditions Generally Aggravated by Exposure: Skin sensitivity, respiratory and pulm ona ry disorders.

Target Organs: Skin, lung s, nervou s and circu latory system s, blood and kidneys.

Carcino genicity: Beryllium has been listed by either the International Agency for Cancer Research (IARC) Monograph or the
National Toxicology Program (NTP) annual report as a potential carcinogen.

EMERG ENCY FIRST AID PROCEDU RES:

INHALATION: Remove person to fresh air. Although no cases are known in which a person stopped breathing as a result of
exposure, if breathing has stopped, administer CPR and obtain medical help.
INGESTION: Have the affected person drink large quantities of water and induce vomiting if conscious. Obtain medical help.
SK IN: Cuts and abrasions can be treated with first aid. Powder and dust can be washed off skin with soap and water. If irritation
persists, obtain medical help.
EYES: Dust or powder should be flushed from eyes with large amounts of clean water. If irritation persists, obtain medical help.


VI REACTIVITY DATA

Stability: Stable.

Co nditio ns to Av oid: None

Incompatibility (Materials to Avoid): Avoid contact with min eral acids and ox idizing agen ts wh ich m ay generate hydroge n gas.
Hydrogen gas can be an explosion hazard.

Haz ardous D ecomposition Produc ts: None under normal conditions of use.
Hazardous Polymerization: Will not occur.


VII SPILL OR LEAK PROC EDURES

Steps to Be Taken in Case Material is Released or Spilled: In solid form this material poses no health or environmen tal risk. If
this material is in powder or dust form, establish a restricted entry zone based on the severity of the spill. Persons entering the
restricted zone must wear adequate respiratory protection and protective clothing appropriate for the severity of the spill. Cleanup
should be conducted with a vacuum system utilizing a high efficiency particulate air filtration system followed by wet cleaning
me thod s. Special care m ust be taken wh en ch ang ing filters on H EPA v acuum cleaners w hen used to cleanup potentially to xic
materials. Caution should be taken to m inimize airborne generation of po wder or du st and avoid contam ination of air and water.

Waste Disposal Method: Dispose o f in accord ance w ith all Federal, State and Lo cal regulation s.


VIII SPECIAL PROTECTION INFORMATION

Respiratory Protection: NIO SH approved high efficiency ca rtridge or su pplied air respirato r is requ ired if b eryllium in air
concentrations ex ceed O SHA standard s.
Ventilation: Use local exhaust to maintain concentrations at or below PEL, TLV.

Protective Gloves: Wear gloves to prevent metal cuts and skin abrasions particularly during handling of wrought forms, solid metal

-Beryllium Copper 2-
sheet, strip or tube.
Safety Glasses: Wear safety glasses, goggles, faces shield or welders helmet when risk of eye injury is present, particularly during
melting, casting, machining, grinding, welding, powder handling, etc.

Other Protective Clothing or Equipment: No protective equipment or clothing is required when handling solid forms. Protective
overgarments or work clothing should be worn by persons who may become contaminated with dusts, fumes, or powders during
activities such as furnace rebuilding, air cleaning equipment bag changes, furnaces tending, etc. Contaminated work clothing and
ove rgarme nts sho uld b e m anaged in such a m ann er so as to pre ven t secon dary exposure to person s such as laun dry operators and to
prevent contamination to personal clothing. Never use compressed air to clean work clothing.


IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: This product poses no health hazard as shipped. There are no special storage
requirements. Wash thoroughly after handling.

Wo rk Practices: Implement engineering and work practice controls to reduce and maintain concentration exposure. Use good
housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or 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.
