OCCUPATION & SAFETY
-
Proper plant design and engineering controls in order to protect
workers from occupational exposure to Lead, including by control of
process and fugitive emissions
-
Appropriate codes of practice/policies/plant hygiene practices for the
workforce and relevant management personnel
-
Required
education & training to workforce about facilities and protective
equipment
-
Regular
monitoring procedures including in-plant/perimeter environmental monitoring
of Air Lead Levels
-
Screening of
workforce Blood Lead Levels at 6 months interval
-
Advance planning
of steps to be taken in case of crossing of prescribed action levels
-
Remedial
actions, which may include engineering and process corrections, job rotation of
workers with High Blood Lead Levels to no-exposure work areas
-
“Reduction
of Lead Blood Level by Chelation Therapy, if required”
-
Dosing of
calcium tablets at regular intervals to the workers to avoid any harm due to
Lead exposure.
Safety Majors
Control Technologies for Air Emissions
Air emissions are measured at the point of creation, this does not take into
account the fate of the emission, for example sulfur dioxide is measured at the
stack, not the site boundary.
The three main components of air emission produced at a Lead smelter/refinery
are dust, metal fumes and sulfur dioxide gas.
Concentrating
Methods for control of Air Pollution (Best Practices):
-
Enclose part or all the process area;
-
Keep ore / raw material damp, where possible;
-
Utilize wet spray suppression systems;
-
Enclose transfer points, equipment and the truck loading operation;
-
Wet and cover truck loads and stored concentrates;
-
Incorporate preventative maintenance on machinery to minimize leaks/leakages;
Processing Site
For loading and unloading areas the following measures should be considered:
-
Enclose the areas, where possible;
-
Where it is not practical to enclose the area, water spray suppression systems
should be installed on the unloading and loading facilities; and
Smelting/Refining
-
Furnace gases should be directed to a fabric filter;
-
Fugitive emissions in the smelter building include dust from uncovered screws
and conveyors, discharges from charge outlets, leaks from furnace covers etc.
Controls include the enclosure of conveyors and other material handling
equipment where practical, operating the building under negative pressure and
having a preventative
