Risk Assessment (DHAs & EPDs)

Before preventative and protection strategies may be identified, a risk assessment is necessary to identify where combustible dust hazards exist within your facility. Fike performs risk assessments around the world to meet NFPA 652 requirements of a Dust Hazard Analysis (DHA) and ATEX 1999/92/EC regulations of an Explosion Protection Document (EPD).

Identify Hazardous Zones

Uses existing process flow diagrams, anecdotal evidence from your experts and a facility walkthrough to understand which areas of your process should be analyzed further and which areas are considered low risk and may largely be ignored.

Analyze Materials & Flammable Atmospheres

Of the identified hazardous zones, further analysis will be perform on where dust is being introduced, conveyed or emitted, where dust clouds develop and where a potentially flammable or explosive atmosphere may occur. Reviews the documented explosibility of the dust handled in the process and performs dust testing if necessary.

Review Ignition Sources & Safeguards

Locates and evaluates potential ignition sources (sparks, static, overheated surfaces and more) which could produce an explosion. Evaluates your safety systems and housekeeping processes to ensure they are compliant and effective. Further opportunities to reduce the risk of combustion will be documented in the final DHA/EPD report.

Create an Action Plan

Prioritizes the areas of your process which should be addressed immediately based on the likelihood of an explosion from occurring and its potential severity. Furthermore, relatively simple or cost-effective areas to improve safety will also be recommended as high priority.

How Can a Risk Assessment be Used to Improve Safety at Your Facility?

Your Fike consultant will use the results from dust testing and identify opportunities within your process to lower the risk of combustion from ever occurring by reducing or removing the following ignition sources:

Open Flames or Heat: welding, cutting, or smoldering items

Electrical Sparks: when a high-voltage device fails or a cable ruptures

Hot Surfaces: combustion equipment, heated processes, motors and lights

Electrostatic Discharge: when equipment or containers are not grounded properly

Frictional Heat or Sparks: overheated bearings or other malfunctioning equipment

Smoldering Material: which slowly combusts internally as long as oxygen is present

Unisolated Explosions: secondary explosions which consume additional fuel and grow in intensity

Rogue Objects: such as a bolt entering the system and creating friction or sparks

Other explosion prevention efforts may include:

Improving housekeeping in areas with dust accumulation
Performing regular maintenance on equipment, such as lubricating bearings, to keep surface temperatures below those found in a Minimum Ignition Temperature (MIT) dust test
Installing spark detectors or reducing risk of static discharge to align with data found in a Minimum Ignition Energy (MIE) dust test
Identify opportunities to mitigate through inerting the process environment with data found in the Limiting Oxygen Concentration (LOC) dust test
