WARNING                
(1) Improper installation or maintenace of tublar glass can cause innediate or delayed glass breakage resulting in bodily injury. To avoid 
breakage observe the  Do's and Do Not's and Use and Care Instructions which are listed in the index, as well as tubular gage
manufacturer's instructions.              
               
(2) If a gage glass breaks, contained substances can be released and glass can be blown out of the unit with great force. Always wear
safety glasses when looking toward a gage or working on a gage glass assembly. Guard against the possibility of fire and explosion.
               
(3) Protect glass from impact, scratches, other surface damage and sudden temperature changes. These can weaken or stress the glass
and lead to breakage.              
               
(4) A good safety practice is to incorporate a protective guard or shield in the gage glass assembly, i.e., a shield between the user
and the gage. Refer to the gage manufacturer's catalog.               
               
(5)Review in detail the Corrosives information which is listed in the index.        
               
(6) Review the disclaimer information which is listed in the index.
