What should msds contain




















MSDSs are prepared by the supplier or manufacturer of the material. It is intended to tell what the hazards of the product are, how to use the product safely, what to expect if the recommendations are not followed, what to do if accidents occur, how to recognize symptoms of overexposure, and what to do if such incidents occur.

These categories are specified in the Controlled Products Regulations and include:. Yes, as long as two conditions are met. All headings and subheadings that are on the MSDS must be addressed by providing the required information or by stating that the information is not available or not applicable, whichever is appropriate.

Second, the statement "This product has been classified in accordance with the hazard criteria of the CPR and the MSDS contains all of the information required by the CPR" must appear under the section heading "Regulatory Information".

Traditionally the intended readers of MSDSs were occupational hygienists and safety professionals. Now the audience also includes employers, workers, supervisors, nurses, doctors, emergency responders and workers. To ensure that MSDS users can quickly find the information that they need, the information should be in an easy-to-read format and written in a clear, precise and understandable manner.

For most people who work with controlled products, there are some sections that are more important than others. You should always read the name of the chemical, know the hazards, understand safe handling and storage instructions, as well as understand what to do in an emergency.

Not necessarily. A lot of health hazard information, for example, is written in general terms. Any generally applicable precautions for safe handling and use which are known to the chemical manufacturer, importer or employer preparing the material safety data sheet, including appropriate hygienic practices, protective measures during repair and maintenance of contaminated equipment, and procedures for clean-up of spills and leaks;.

Any generally applicable control measures which are known to the chemical manufacturer, importer or employer preparing the material safety data sheet, such as appropriate engineering controls, work practices, or personal protective equipment;. The date of preparation of the material safety data sheet or the last change to it; and,. The name, address and telephone number of the chemical manufacturer, importer, employer or other responsible party preparing or distributing the material safety data sheet, who can provide additional information on the hazardous chemical and appropriate emergency procedures, if necessary.

If no relevant information is found for any given category on the material safety data sheet, the chemical manufacturer, importer or employer preparing the material safety data sheet shall mark it to indicate that no applicable information was found. Where complex mixtures have similar hazards and contents i. The chemical manufacturer, importer or employer preparing the material safety data sheet shall ensure that the information recorded accurately reflects the scientific evidence used in making the hazard determination.

If the chemical manufacturer, importer or employer preparing the material safety data sheet becomes newly aware of any significant information regarding the hazards of a chemical, or ways to protect against the hazards, this new information shall be added to the material safety data sheet within three months.

If the chemical is not currently being produced or imported the chemical manufacturer or importer shall add the information to the material safety data sheet before the chemical is introduced into the workplace again. Chemical manufacturers or importers shall ensure that distributors and employers are provided an appropriate material safety data sheet with their initial shipment, and with the first shipment after a material safety data sheet is updated;.

The chemical manufacturer or importer shall either provide material safety data sheets with the shipped containers or send them to the distributor or employer prior to or at the time of the shipment;. If the material safety data sheet is not provided with a shipment that has been labeled as a hazardous chemical, the distributor or employer shall obtain one from the chemical manufacturer or importer as soon as possible; and,.

The chemical manufacturer or importer shall also provide distributors or employers with a material safety data sheet upon request. Distributors shall ensure that material safety data sheets, and updated information, are provided to other distributors and employers with their initial shipment and with the first shipment after a material safety data sheet is updated;. The distributor shall either provide material safety data sheets with the shipped containers, or send them to the other distributor or employer prior to or at the time of the shipment;.

Retail distributors selling hazardous chemicals to employers having a commercial account shall provide a material safety data sheet to such employers upon request, and shall post a sign or otherwise inform them that a material safety data sheet is available;.

Wholesale distributors selling hazardous chemicals to employers over-the-counter may also provide material safety data sheets upon the request of the employer at the time of the over-the-counter purchase, and shall post a sign or otherwise inform such employers that a material safety data sheet is available;. If an employer without a commercial account purchases a hazardous chemical from a retail distributor not required to have material safety data sheets on file i.

Wholesale distributors shall also provide material safety data sheets to employers or other distributors upon request; and,. Chemical manufacturers, importers, and distributors need not provide material safety data sheets to retail distributors that have informed them that the retail distributor does not sell the product to commercial accounts or open the sealed container to use it in their own workplaces.

The employer shall maintain in the workplace copies of the required material safety data sheets for each hazardous chemical, and shall ensure that they are readily accessible during each work shift to employees when they are in their work area s. Electronic access, microfiche, and other alternatives to maintaining paper copies of the material safety data sheets are permitted as long as no barriers to immediate employee access in each workplace are created by such options.

Where employees must travel between workplaces during a workshift, i. In this situation, the employer shall ensure that employees can immediately obtain the required information in an emergency. Material safety data sheets may be kept in any form, including operating procedures, and may be designed to cover groups of hazardous chemicals in a work area where it may be more appropriate to address the hazards of a process rather than individual hazardous chemicals.

If the MSDS is not available, you should send the material's label or a labelled container of the material, if it is small enough. Emergency medical responders need to know what the material is and what First Aid Measures have been recommended and used.

Occasionally, the MSDS has additional instructions or a Note to Physician which may be useful to the emergency doctor. This section describes any fire hazards associated with the material and fire fighting procedures.

The information can be used to select the appropriate type of fire extinguishers and to plan the best response to a fire for a particular work site. Much of the information is intended for firefighters and emergency response personnel. If the material is a potential fire hazard, you should also refer to Section 7 for special handling precautions. The information in this section, combined with information from Section 7 Handling and Storage and Section 10 Stability and Reactivity can be used to determine where a certain material should be stored for example, flammable liquids should be stored in specially designed facilities away from incompatible chemicals.

General instructions for responding to an accidental release or cleaning up a spill are provided in this section. Specific information, such as recommended absorbent materials for spill cleanup, may be included. The information is intended to be used mainly by emergency responders and environmental professionals. In this section, you will find general precautions necessary for the safe handling of the material, including any equipment that may be required.

All possible hazards fire, reactivity, health and environmental need to be considered when developing safe handling procedures. For example, for dispensing a flammable liquid, the MSDS may suggest electrical grounding and bonding of containers. The storage recommendations provided in this section provide a good starting point for deciding where and how materials should be stored e. This section provides information which is used to develop procedures and practices for working safely with the material.

Most MSDSs are written to address all reasonably anticipated uses of the material. Because they must address such a wide range of usage situations, the information may not be entirely applicable to your job. A health and safety professional can help you in interpreting the information and assessing its relevance. Exposure guidelines, if available, are given for each component. Some manufacturers provide their own recommended exposure limits for their products.

Legal regulated exposure limits in your jurisdiction provincial, territorial or federal may be different from those listed on the MSDS. Health and safety professionals use exposure limits as standards when air sampling is conducted.

Engineering control systems reduce potential hazards either by isolating the hazard or by removing the hazard from the work environment. They either control the potential hazard at its source local exhaust ventilation , remove it from the general area general ventilation or put up a permanent barrier between the worker and the potential hazard isolation or enclosure.

Engineering control systems are important because they are built into the work process to reduce the hazards automatically. Substitution of a less hazardous material or industrial process is always the best way to reduce a hazard and should be considered first.

Engineering control systems are the next best option and are preferred over other control measures such as the use of personal protective equipment. You need to make sure that engineering control systems recommended for your job are properly checked and maintained and that they are operating when you are working with the material.

If there are changes in the process or materials, the controls may have to be changed as well. Depending on the job you are doing and the type of material you are handling, you may need various levels of eye protection e. Skin protection includes items such as gloves, aprons, full body suits, and boots. The MSDS should tell you the types of rubbers or other materials that provide the best protection against the product you are using.

No one material acts as a barrier to all chemicals. It is also important to consider the temperature conditions and the need for materials not easily cut or torn. Sometimes, the MSDS may simply advise you to use impervious resistant materials.

In this case, you need to find out which specific materials are best. You may be able to obtain this information from the product supplier or manufacturer or from a protective clothing supplier or manufacturer. It is also important to maintain your protective clothing or gloves properly and replace them when necessary.

There are many different types of respirators. One type may be effective against some chemicals but may provide little or no protection against others. Selecting the best respirator for you can be quite complicated. Usually a qualified person must carry out a detailed assessment of the workplace, including all chemicals used and their airborne concentrations and forms. Consequently, complete respiratory protection guidelines generally cannot be given on the MSDS.

If respirators are required at your work site, a complete respiratory protection program including respirator selection, fit testing, training and maintenance is necessary. The relevant regulatory and consensus standards should be consulted. This subsection provides general hygiene information that is usually not material specific, e. You should check that the description physical state and appearance of the material on the MSDS is the same as the material you have.

If it isn't, you may not have the correct MSDS. Alternatively, the material may be old or may have decomposed during shipping or storage. In either case, the information on the MSDS may not apply, and you should obtain additional advice.

The rest of the information in this section is used to help determine the conditions under which the material may be hazardous.

Technical specialists use this information to develop specific work site procedures for exposure control, storage, handling, fire fighting, spill clean-up, etc. This section of the MSDS describes any conditions under which the material is unstable or can react dangerously and conditions that should be avoided. Unstable materials may break down decompose and cause fires or explosions or cause the formation of new chemicals that have different hazards.

Conditions such as heat, sunlight, and aging of the chemical may cause unstable chemicals to break down. Some chemicals are hazardous because they can polymerize or undergo a chain reaction.
