MALLORY TUNGSTEN-BASED MATERIALS
The only Health & Safety problems associated
with these products arise during machining.
If the machining operation is carried out in dry conditions (without lubricant) metal dust particles are likely to be generated. There could, therefore, be a potential hazard from respirable dust and nuisance particulates. Inhalation of metal dust must be avoided and one must prevent such dust particles from reaching the eyes, nose or throat of any person.
The occupational
exposure limits for the metals contained within the Mallory products are as
follows:
|
|
Long-term Exposure limit (8 hour TWA value) mg m-3 |
Short-term Exposure limit (10 min TWA value) mg m-3 |

We would recommend
local exhaust ventilation if dust levels approach half these OELs.
Normal workshop
safety practice and conventional equipment are usually adequate to prevent hazard
from metal dust particles. When
necessary, machines should be provided with cowls over the work area with efficient
dust extraction. Operators may
wish to take the additional precaution of wearing dust masks and protective
goggles.
It is essential
that personnel handling our products, and their supervisors have all the relevant
safety information. We rely on you to fulfill your obligations under the Health
& Safety at Work Act by passing on our safety information to the right people
in your organisation.
