What is MSDS? 7 Main Points In MSDS That You Cannot Overlook


According to the Department of Occupational Safety and Health Malaysia, preparing a proper Material Safety Data Sheet (MSDS) is stated under the Occupational Safety and Health (Classification, Labelling and Safety Data Sheet of Hazardous Chemicals) Regulation 2013, which is also known as CLASS Regulation. 

A MSDS is a database that contains information about the potential hazards of a chemical substance (health, combustion, reactivity, and the environment), as well as how to deal with it safely. In terms of content details, the MSDS is much more comprehensive than the label. 

MSDSs are produced by the supplier or seller of the products. Its aim is to clarify the dangers of the product, how to use it correctly and what to expect if the instructions are not followed. It will also guide us on what to do if an accident occurs and how to diagnose overexposure effects.

When managed goods enter the workplace, employers must ensure that they have an up-to-date (less than three-year-old) MSDS. Workers who are exposed to the regulated substance, as well as the health and safety committee or delegate, must have access to the MSDSs. If a managed substance is created at work, the employer is responsible for preparing an MSDS for each of these products. 

Employers are permitted to computerize MSDS documents as long as all workers have access to them and are instructed on how to operate the computer. The devices are to be maintained in good working order and the employer makes a hard copy of the MSDS accessible to the employees or safety and health committee/representative upon request. 

Content of MSDS 

The content of MSDS is according to the policies of the countries. However, the few basic content that must be included in the MSDS are: 

1. Hazardous Identification with the Content of Mixture 

The chemical names and amount of the potentially dangerous substances.

2. Physical Data 

This section should include information about how it appears and how it will behave when used, stored, spilled, and how it will react to other items indicated by:

– The state it is in, for example, liquid

– The product’s odour and look

– The specific gravity, vapour density, evaporation rate, and temperature 

– The boiling and freezing point

– The volume of concentration, as the higher the concentration is, the higher the achievable air pressure.

– The smell threshold, which is the lowest chemical concentration in the air that can be detected by the sense of smell

– The pH, which reflects the product’s caustic or irritant characteristics.

3. Fire or Explosion Hazard Data 

The temperature and environmental circumstances that might cause the chemical to catch fire or explode.

4. Reactivity Data

Information on the chemical instability of a product and the substances it may react with .

5. Information about the Toxicity of the Material 

The negative consequences of exposure and long term / short term effect towards workers if PPEs are not properly worn.

6. Preventive Measures 

Instructions on the products safety, handling, and storage.

7. First Aid Measures

First-aid procedures should be carried out in the right order.

What happens when you recycle your used oil in Malaysia?

The diminishing of fossil fuel sources, growing demand and cost of petroleum-based fuels, and environmental hazards in these few decades have motivated the increase of refining waste oil to recycled fuel oil. You would probably be wondering, is all this mineral oil including the engine oil used for your car a renewable resource? In Pentas Flora, our answer is YES. 

In fact, waste oil or used oil should not be thrown away, especially disposed of in the ocean. Hence, the used oil can be recycled again and again through several refining processes. The recycled fuel oil are used for many purposes (Maceiras et al., 2017).

These include: – Lubricants, hydraulic or transformer oil 

– Rerefine into fuel oils

– Industrial burner oil 

– Mould oil 

– Heavy duty diesel 

The process of re-refining of used oil will go through dewatering which includes removing the accessing water within the oil. The used oil will then go through further steps including filtering and demineralisation to remove any solids in the oil. Then, it will proceed to the next step which is propane deasphalting to remove the heavier bituminous fractions and lastly distillation to  produce as the final product. 

Recently, recycling and utilizing of waste oils have received significant attention all over the world, since waste lubricating and hydraulic oils are considered toxic and hazardous waste due to the presence of metal particles (Beneficial & Skills, 2016). Hence, it is very important to draw the public attention to this topic.
