EXPLOSION PREVENTION and PROTECTION

Knowledge of the explosion parameters of flammable gases and vapors as an important part of the explosion risk assessment at the workplace – Paulina Flasińska – Institute of Industrial Organic Chemistry – Warsaw, Poland – Ostrava 14-15 May 2013

What should be considered?

Chemical and physical properties of the substance,

Amount and properties of a possible explosive atmosphere,

Properties of ignition sources,

Environment geometry,

Strength of the materials for the apparatus construction,

Personal protective equipment,

Physical properties of objects

How to assess the risk?

Identify hazard,

Determine the probability of an explosion occurrence,

Identify possible sources of ignition

What might be the effects of explosion?

Fires,

Heat radiation,

Fragments recoil,

Pressure wave,

Release of hazardous materials

How to eliminate or minimalize the risk?

Minimalize amount of flammable substance,

Replace flammable substance its less flammable equivalent,

Apply inert agents
