WASTE DISPOSAL
Ability to dispose of waste:
•
Contaminated filters
•
Metal powder
•
Clothes and paper towels used for cleaning
Need to have closed metal containers for waste and the ability to store the waste containers, if possible, in a closed
environment outside the production facility.
Waste materials must be disposed of in accordance with all local, state and federal regulations.

FIRE SUPPRESSION
The facility must have a Class D fire extinguisher and a fire blanket present in the work area.
The automatic sprinkler system must be disabled in areas where reactive metals are used or stored. Several of the materials,
(magnesium, titanium, aluminum, etc.) will react with water to produce hydrogen. With the sprinkler system disabled, local
building code may require the installation of an inert gas system for fire suppression.
Although a class D is required for metal fires, do not neglect to have a class ABC portable on hand as well for
non-metal fires that class D is not effective against.

SPECIAL CONSIDERATIONS WHEN USING REACTIVE METALS
The modifications listed in this section must be observed if you will be using reactive metals in your facility. The following are
considered to be reactive metals:
•
Titanium and Titanium alloys
•
Aluminum and Aluminum alloys
•
Magnesium and Magnesium alloys
•
Pure Nickel
•
Pure Zinc
The automatic sprinkler system must be disabled in areas where reactive metals are used or stored. Several of the materials
will react with water to produce hydrogen. With the sprinkler system disabled, local building codes may require the installation
of an inert gas system for fire suppression.
Filters cannot be used in the ventilation system for the room. Fine metal particles will collect in the filter and become a source
of auto-igniting fires.
