I relize this should be posted in the "safety procedures and chemicals" section, but if some are like me i usually read read here mostly, so if the moderator feels this should by moved well thats ok too.
With that said we had our saftey meeting today and just had a bit of a review on things today, And I think we should all be reminded of how dangerous some of the chems are that we use.
and this is one of the things we talked about and one of my crew chiefs brought this up, that we some times become complacent with our chemical mixing so as a reveiw/reminder i'd like to post this to all vets and newbies...
SPECIAL MIXING AND HANDLING INSTRUCTIONS
considerable heat is generated when product is mixed with water.Therefore, when making solutions always carefully follow these steps:
ALWAYS
wear ALL protective clothing. NEVER add water to product. ALWAYS add product, with constant stirring, slowly to surface of lukewarm (80 100*F) water, to assure product is being compltely dissovled as it is added.
Product can react EXPLOSIVELY with acids, aldehydes and many other organic chemicals, add product VERY gradually, while stirring constantly. If product is added too rapidly, or without stirring, and becomes concentrated at the bottom of mixing vessel, excessive heat may be generated, resulting in DANGEROUS boiling and spattering, and a possible IMMEDIATE AND VIOLENT ERUPTION of highly caustic solution.
ALWAYS empty and clean containers of all residues before adding product, to avoid possible EXPLOSIVE reaction between product and unknown residue.
Thanks be safe it pays!!
