This hint is about MSDS -- which stands for Material Safety Data Sheet. These are bulletins that give information on the properties of the chemicals that cleaning professionals use. They are prepared by the company that manufactures or imports the chemical.
You can get a great deal of practical information on the hazards of a substance, how to handle it safely, emergency procedures in case of exposure and so on from a MSDS. MSDS's are required by OSHA (Occupational Safety and Health Administration). OSHA recommends nine different sections in a MSDS:
Section 1 Chemical Identification
This section includes the chemical name, trade name, chemical formula and the chemical manufacturer's name, address and emergency phone number.
Section 2 Hazardous Ingredients
This section lists any hazardous ingredients found within the chemical. In this section you might also see the terms TLV (Threshold Limit Value) and PEL (Permissible Exposure Limit). Both terms are used to express the highest airborne concentrations of a chemical to which most persons can safely be exposed during a normal workday. The CAS (Chemical Abstract Service) numbers listed in this section identify specific chemicals according to information published by the American Chemical Society.
Section 3 Physical Data
This section lists important physical properties of the chemical such as its boiling point, vapor density, percent volatile, appearance, and color. This information helps determine the degree of hazard associated with the chemical in different work environments. For example, vapor density describes the weight of a vapor relative to an equal volume of air (air=1). If a chemical has a vapor density greater than 1, its vapor will be heavier than air and tend to fall and concentrate near the floor.
Section 4 Fire and Explosion Data
This section helps you determine the chemical's flash point, which is the temperature at which a chemical will release enough flammable vapor to ignite. Chemicals that ignite at or below 100 deg. F are classified as flammable. In addition, this section usually lists the chemical's upper and lower flammability limits, proper types of extinguishing media required to safely extinguish the fire (example: carbon dioxide, water, foam, etc.), special fire fighting procedures, and any unusual fire or explosion hazards.
Section 5 Health Hazard Data
This section describes health effects associated with overexposure to the chemical through ingestion, inhalation, and skin or eye contact. The information may include the acute (immediate) and chronic (long-term) effects of overexposure to the chemical, whether the chemical is a known carcinogen (cancer-causing agent), emergency and first aid procedures to follow in case of overexposure, and medical conditions that may be aggravated upon contact with the chemical.
Section 6 Reactivity Data
The information in this section helps you determine if the chemical will react with other chemicals or under certain conditions. Chemical that are reactive (unstable) may explode, burn, or release toxic substances under certain conditions. This section usually tells you if the chemical is stable or unstable and lists any chemicals or substances that might be incompatible with the chemical.
Section 7 Spill or Leak Procedures
This section lists the procedures to follow when a chemical is accidentally released or spilled. It will also cover types of clean-up and protective equipment needed to safely contain or clean up a spill as well as proper ways to dispose of the chemical.
Section 8 Special Protection Information
This section lists the personal protective equipment (respirators, gloves, eye protection, etc.) and other precautions the manufacturer recommends for work with the chemical. Remember, there are various types of protective equipment that are specially designed for certain tasks. Consult your supervisor to ensure you are using the correct type for the work you are performing.
Section 9 Special Precautions
The last section usually discusses special precautions to be taken during handling and storage of the chemical. Also, this section will usually discuss any other health and safety concerns that have not been mentioned elsewhere in the MSDS.
