What Is MSDS of Tungsten Heavy Alloy?

Material Safety Data Sheet (MSDS) is a table about data regarding the properties of a particular substance, which may concern instructions for the safe use and potential hazards associated with a particular material or product. Therefore, MSDS of tungsten heavy alloy is important and necessary for chemicals users.
The sheet of MSDS of tungsten heavy alloy aims to offer workers and emergency personnel with procedures for handling or working in a safe way, and MSDS of tungsten heavy alloy includes information such as physical data (melting point, boiling point, flash point, hardness, ultimate tensile strength, density, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill handling procedures. The exact format for MSDS of tungsten heavy alloy can vary from countries to countries by respective national requirement.

For example, below is part of the MSDS of Tungsten Heavy Alloy:

SECTION 3. HAZARDS IDENTIFICATION

The terms "hazardous" and "hazardous materials" as used within this MSDS should be interpreted as by, and in accordance with, the OSHA Hazard Communication

Standard (29CFR1910.1200) including cited appendices, lists, references, etc.

Primary routes of entry:	Inhalation, ingestion, skin or eye contact (for dusts, mists, powder and fume)
Effects of overexposure:	No specific data, testing or information has been found for the chemical compounds that comprise this product. However, general comments are made below for the individual elements.
Carcinogenic assessment:	Cobalt - IARC 2B; Nickel - IARC 2B, NTP 2;

Note: IARC 2B - The agent is possibly carcinogenic to humans. This category is generally used for agents for which there is limited evidence in humans in the absence of sufficient evidence in experimental animals. MSDS of tungsten heavy alloy may also be used when there is inadequate evidence of carcinogenicity in experimental animals.

NTP 2 - Substances or groups of substances which may reasonably be anticipated to be carcinogens. "Reasonably anticipated to be carcinogens" defines carcinogens for which there is limited evidence of carcinogenicity in humans and/or sufficient evidence of carcinogenicity in experimental animals.
