 Wear types of PPE in any combination as needed to protect exposed body parts to heat or metal splatter, as determined by the hazard assessment for each  work activity.


Don’t:


 Forget to wear safety glasses with side protection when face


Consider aluminized PPE when exposed to high heat and spark producing opera- tions such as lancing, tapping, slagging or activities where molten metal splash is possible.


Don’t:


 Tuck pant legs inside boots or spats.  Wear Nomex, as molten metal tends to stick to the  fabric.


Wear polyester, nylon or other man-made materials that  can melt and possibly ignite.


Wear phosphorus-treated cotton (for nonferrous metals) because molten metal sticks to the fabric. Many flame  resistant cotton fabrics use a phosphorus-based treatment.


Wear clothing that may trap molten metal or sparks,  such as cuffs, open pockets, loose legging tops, etc.


Wear any sort of metal jewelry.


Eye and Face Protection in Pouring Operations PPE items are available to protect you from head to


toe. Identify the type of equipment that is available and required. For protection of the face and eyes, potential haz- ards are eye and face injuries from foreign bodies, molten metal splash and chemicals, and damage from infrared and/ or ultraviolet radiation. Safety glasses with side shields are minimum secondary


protection that should be used for all metalcasting opera- tions, especially melting. T e following types of additional


PPE should be used for the eyes and face:  Full face shield, thermal/infrared with a gold  tint/wire mesh.


 Full face shield, polycarbonate or #40 steel wire mesh.


These molten metal handlers are protected with full face shields, gloves, and coats.


obstructions, burns from physical contact with molten metal splash, sparks, fl ames and/or hot surfaces, foot injuries from fall- ing or rolling objects and scrapes, cuts and abrasions. When head protection is needed, workers should utilize


Tinted glasses specific to the type of metal (iron—shade #3‒#5 green; steel—shade #8 green or #6 cobalt blue; brass/ bronze—shade #3‒#5 green or shade #3 green with #3 aluminized face shield or shade #6 cobalt blue (half lenses); aluminum and magnesium—clear, no tint.


Dos and Don’ts in Melting Face and Eye Protection


Do:


 Use appropriate darker shades of glasses for intense  radiant energy.


Switch to a lower shade number of un-tinted lenses when leaving the molten metal area or during extended  periods when no molten metal viewing is required.


Choose a lower shade number for glasses when molten  metal viewing is momentary or incidental.


Use a full face shield (such as polycarbonate or #40 steel mesh) when exposed to a potential hazard of molten metal splash such as furnace charging, tapping or ladle pouring.


a thermal rated hard hat, with a cotton or wool cap or an aluminized hood. For hand protection, workers should use the following


materials for mitts, cover mitts, cover pads or gloves: leather, cotton, wool, Kevlar, wool-lined Kevlar, aluminized fabric or other heat resistant materials. For primary protection of the feet,


workers should use metatarsal safety shoes or shoes with heat resistant soles.


Dos and Don’ts in Head, Hand and Foot Protection


Do:


 Use a thermal rated hard hat with a cotton or wool cap to provide protection  from minor metal splatter.


Consider the need for dexterity and grip security while operating equipment when choos- ing safety gloves.


Metatarsal safety shoes or engi- neer boots offer protection.

protection is worn.  Choose eye protec- tion that is too dark as it


may reduce visibility and create hazards such as tripping.


Protection in Pouring Operations for Head, Hands and Feet


T e hazard assessment should consider potential head, hand and foot hazards found on the melt deck, including head injuries from falling objects, moving equipment and/or overhead
