Emergency Overview:

Use of grinding wheels may create dust and high noise levels. Avoid inhalation and prolonged exposure to noise.

Potential Health Effects:

          Eye:

Dust and flying debris may irritate/damage eyes.

Chronic exposure may irritate eyes.

          Skin:

Dust and Flying debris may irritate/damage skin.

Chronic exposure may cause skin irritation.

          Ingestion:

Should not occur.

          Inhalation:

Grinding causes wheel to break down resulting in dust classified by OSHA as inert or nuisance dust and would have the pulmonary effects of inert dust. Note the carcinogen reference under toxicity. May cause coughing, shortness of breath.

Chronic exposure may affect breathing capacity.

Chronic/Carcinogenicity:

          NTP:

Not tested

          OSHA:

Not regulated

          IARC:

Not listed

Medical Restrictions:

None known

General Information:

Immediately cease grinding. Remove contaminated clothing and move to well ventilated area. Rinse with copious amounts of water if irritation continues.

Eye:

If irritation occurs, wash eyes immediately with large amounts of water, occasionally lifting upper and lower lids until no evidence of material remains (approximately 15-20 minutes).

Get medical attention immediately.

Skin:

If irritation or rash occurs, remove contaminated clothing and shoes immediately. Wash affected area with soap or mild detergent and large amounts of water until no evidence of material remains (approximately 15-20 minutes).

Get medical attention immediately.

Ingestion:

Get medical attention immediately.

Inhalation:

If symptoms of pulmonary involvement develop (coughing, wheezing, shortness of breath) remove from exposed area to fresh air immediately. If breathing has stopped, perform artificial respiration.

Keep affected person warm and at rest. Get medical attention immediately.

Negligible fire hazard. However, accumulation of powder or dust from grinding may create a fire hazard.

Flash Point:

N/A

Extinguishing Media:

For localized powder fires, smother with dry sand, dry dolomite, sodium chloride or soda ash.

Extinguishing Procedures:

Move container from fire area if possible. Cool  containers exposed to flame with water from side until well after fire is out. For massive fire in cargo area, use unmanned hose holder or monitor nozzles; else withdraw and let fire burn.

Use soda ash, powdered sodium chloride, or suitable dry powder.

Avoid breathing fumes from burning material.

Fire fighting personnel must use proper respiratory protection.

Cleaning:

Clean up dust or powder from grinding with a minimum of dust generation and place into suitable clean, dry containers for later disposal or reclamation. Residue should be cleaned up using a high-efficiency particulate filter vacuum or wet clean up.

Use appropriate respiratory protection.

Disposal Method:

Disposal should be made in compliance with federal, state and local environmental regulations.

Handling:

Avoid dispersion of dust from grinding in air. Finely divided particles, dust, or fumes may be flammable or explosive. Keep away from sparks or ignition sources.

Storage:

Store in a secure, clean, dry cool area.

Other Precautions:

Wash hands thoroughly after handling, before eating or smoking. Do not shake clothing, rags or other items to remove dust. Dust should be removed by washing or vacuuming.

Periodic medical examinations are recommended for individuals regularly exposed to dust or mist.

Engineering Controls:

Provide local exhaust ventilation to meet published or recommended exposure limits as per TLV-TWA.

Personal Protection:

          Eye/Face:

Safety glasses with side shields or goggles are recommended. Where there is any possibility that an employee’s eyes may be exposed to this substance, the employer should provide an eye-wash fountain within the immediate work area for emergency use.

          Skin:

Protective clothing not required. However, avoid repeated or prolonged contact with this substance.

Protective gloves are not required but recommended.

          Respiratory:

Respiratory protection should be provided based on the materials being ground. Consult the appropriate MSDS for guidelines.

Fire Fighting:

Self-contained breathing apparatus with a full face piece, operated in pressure-demand or other positive-pressure mode
