Sample Hazard Analysis for Beryllium Use

 

 

If yes is selected for any entry in the checklist, describe the controls below the checklist.  Where multiple “yes” selections exist, a written Standard Operating Procedure (SOP) is indicated

 

Hazard Analysis Checklist

Hazard

Examples

Y/N

Controls

What is the source of the beryllium?

Component received from another Lab.

Component ordered from supplier.

 

MSDS

Notify IH Group who will enter into Lab chemical inventory

Is the beryllium component protected, or is it removable so that it can come into contact with unprotected skin?

Beryllium windows

Beryllium oxide heat sinks in electronic equipment

 

Components housed inside labeled enclosure. 

Exposed beryllium surfaces coated to reduce skin contact, aluminum or other metal “sandwich.”

personal protective equipment, such as gloves, disposable suits

Describe how the beryllium is to be used.

Storage, Beamline component, Known to be present in electronic component, Used as alloy, e.g., beryllium copper breakdown of beamline after experiment, installation into beamline

 

Inventory and control all Beryllium components that are not contained and therefore protected from contact by the skin in a locked storage area*

Warning labels

Will airborne particles be present, which could be inhaled?

Cutting, grinding, sanding, soldering, heating

 

SOP

Machining: capture dust at the machine tool interface.

Respirators, HEPA filter vacuum to be used as local exhaust, laboratory fume hood

Can the component fail explosively, causing inhalation and skin contact?

Rectifier explosion

 

Emergency response procedure, decontamination procedure

At the end of the job, is there potential for the component’s protective coating to be eroded?

Burnoff of protective varnish

 

Sampling for removable beryllium by IH Group.

 

Hazard

Examples

Y/N

Controls

At the end of the job, is there potential for ancillary equipment to be contaminated with beryllium dust?

Vacuum vessels with internal beryllium windows may be contaminated with beryllium dust.

 

Decontamination required by IH Group.

Are you sending a beryllium component off site?

Risk of exposure if package opened during shipment

 

Give package to IH Group for shipment as hazardous material.

 

* Does not apply to beryllium copper alloys
