in case there are no critical reactions between chemicals and such storage is safe concerning fireprevention
requirements.
Contractor will provide material safety data sheets (MSDS) for all hazardous materials used in the
process. They are all solid materials, liquid and gaseous chemicals and catalysts used and consumed
in the process.
One of the fundamental arrangements concerning environmental protection from generated solid
wastes is creation of a landfill for their disposal there.
In this regard the following decisions of the wastes managing issues are possible.
Effective work regarding wastes managing provides in every instance for a number of logistical
arrangements and the processes performance taking into account the following:
• list of wastes according to their types and phase;
• physicochemical properties of both specific components (types) and their mixes;
• wastes generation nature and volume;
• possibility and appropriateness of creation of the facilities for complex neutralization and
processing of wastes as well as disposal of wastes to off-site consumers as recyclable
energy resources;
• state of natural environment in the region and the local socioeconomic conditions;
• level of industrial development in the region, transportation development, etc.
Possible directions of wastes managing are following:
• reduction of wastes volume during their generation;
• separation and concentration;
• off-site disposal;
• recycling;
• processing (including valuable components recovery, toxic components neutralization or
conversion into the less hazardous state for further disposal);
• temporary storage at the specially arranged site;
• secure disposal.
Reduction of wastes volume during their generation is the most preferable direction, since
expenditures for these actions are less as compared with the possible expenses for wastes storage,
neutralization, etc. However there are restrictions concerning technologies at the every stage of
production development.
Separation and concentration of wastes. Separation and concentration of hazardous wastes
allow reducing of their total volume but weight of dangerous components remains the same. For
instance dehydration is used for higher concentration resulting in the less volume of transported and
disposed wastes. Besides during dehydration concentrated volatile components of wastes might
evaporate.
As soon as expenditures for disposal are as a rule in direct proportion to the volume (weight) of
