JSA stands for Job Safety Analysis. It is a process of identifying potential hazards and risks associated with a specific job or task.

• JSA involves breaking down a job into individual steps and analyzing each step for potential hazards and risks.

• The goal of JSA is to identify and eliminate or mitigate potential hazards before they cause harm.

• JSA is typically used in industries such as construction, manufacturing, and healthcare.

• Risk assessment, on the other hand, is a broader ...read more

Fire point is the temperature at which a fuel ignites and continues to burn, while flash point is the temperature at which a fuel ignites momentarily.

• Fire point is higher than flash point.

• Flash point is used to classify flammable liquids.

• Examples of flash point: gasoline (−43 °C), diesel fuel (52 °C), kerosene (38 °C).

• Examples of fire point: gasoline (246 °C), diesel fuel (74 °C), kerosene (74 °C).

Fire is a chemical reaction that releases heat, light, and various gases. It can be classified into different types based on the fuel involved.

• Fire is a rapid oxidation process that occurs when fuel, heat, and oxygen are present.

• It releases energy in the form of heat and light.

• Fire can be classified into five main types: Class A, Class B, Class C, Class D, and Class K.

• Class A fires involve ordinary combustible materials like wood, paper, and cloth.

• Class B fires involve flamma...read more
