Routes of Entry:

Routes of Entry

Skin? No
Ingestion? Yes

ACGIH Threshold Limit Value (1988-1989):  Total dust containing no asbestos and less than 1% silica - 10mg/m3

OSHA PEL (Transitional):  Total dust 50 million particles per cubic foot.

OSHA PEL (Final): Total dust 10mg/m3, respirable dust 5 mg/m3.

Effects of Overexposure:

Effects of Overexposure
Acute: This material contains calcium silicates and calcium aluminates, is alkaline and can dry the skin and may cause caustic burns.  Direct contact with the eyes can cause irritation.  Inhalation can irritate the upper respiratory system.
Chronic: Abrasive dusts can cause inflammation of the lining tissue of the nose and inflammation of the cornea.  Hypersensitive individuals may develop an allergic dermatitis.
Signs and Symptoms of Exposure: Redness to skin, minor irritation to eyes, nose and throat.
Emergency First Aid Procedures: Irrigate (flood) eyes immediately and repeatedly with clean water.  Wash exposed skin areas with soap and water.  Apply sterile dressings.  Remove from further exposure those individuals who develop signs or symptoms.  Consult a physician immediately.

SECTION VII - Precautions for safe handling and use

If Blastox®  is spilled it can be cleaned up by using normal dry methods. Use protective clothing to prevent skin exposure. Rubber boots, rubber gloves, tight fitting goggles and OSHA, MSHA, or NIOSH approved respirators should be used. Emergency procedures are not required.

Blastox® can be treated as a common waste for disposal or returned to the container for later use if it is not contaminated or wet.

SECTION VIII - Control measures

Observe ANSI standard Z88.2-1980 "Practices for Respiratory Protection," and standard Z9.4-19804 "Ventilation and Safe Practices of Abrasive Blasting Operations."

Local exhaust can be used to control airborne dust levels.

Use protective clothing to prevent skin exposure. Rubber boots, rubber gloves, tight fitting goggles and OSHA, MSHA, or NIOSH approved respirators should be used.

Following work with Blastox®, workers should wash with soap and water and apply a moisturizing cream.
