Chemical Risk & Safety Phrases

It is known as risk and safety statement. If you work in a wood furniture production environment, there are lots of chemicals exposure around you that can easily enter the body and endanger your health and safety at work.
Paint and other finishing materials, various types of wood glue, wood preservative solutions, and other cleaning agents are example of chemicals that might contains dangerous substances. Therefore, it is important for you to know the chemical safety codes and phrases that are usually written on cans or containers with safety labels.

For an example, Hydrochloric Acid has a risk type of R: 34-37 which means it contains a risk of 'fire (on skin)' and 'respiratory system irritation'. Information about this risk and safety cautions MUST be included in the MSDS (Material Safety Data Sheet) of chemical.

When the chemical's risk list is included in the MSDS, it will be very useful for users to immediately take preventive actions wherever there are chemicals or hazardous substances exposure. In the wood industry, the MSDS must be available at the storage place and translated into local language.
