First-aid measures

Description of first aid measures
EYE CONTACT: Ensure that contact lenses are removed before rinsing eyes. Separate eyelids, wash the eyes thoroughly with water (15 min). Seek medical attention if irritation persists
INHALATION: Move person to fresh air. Seek medical attention.
SKIN CONTACT: Remove any contaminated clothing. Wash skin with water and soap immediately and rinse thoroughly. Seek medical attention if irritation persists.
INGESTION: Rinse mouth with water. If swallowed, induce vomiting under medical supervision.

Most important symptoms and effects, both acute and delayed
Typical clinical manifestations of lead poisoning include weakness, irritability, asthenia, nausea, abdominal pain with constipation, and anaemia.

Indication of any immediate medical attention and special treatments needed
Symptoms of poisoning may occur after several hours; therefore medical observation for at least 48 hours after the accident is recommended.

Methods and materials for containment and cleaning up
Avoid generation of dust. Vacuum or sweep up into containers marked and suitable for disposal as hazardous waste. Wash spillage area after cleanup with large amounts of water.

Handling and storage

Precautions for safe handling
Ensure there is exhaust ventilation of the area. Avoid breathing dust, mist, or gas. Avoid contact with skin and eyes.
Handle lead material in such a way, that distribution of dust is minimized. Use proper industrial hygiene. Do not inhale fumes or dust. Thorough dedusting. Ensure good ventilation/extraction at the workplace. Open and handle receptable with care.
Procedural and control technologies are used to minimise emission and any resulting exposure (when handling the substance, during cleaning and maintenance works and in case of accident). All procedures are well documented and supervised by the site operator.
Only properly trained and authorised personnel may handle the substance.

Conditions for safe storage, including any incompatibilities
No special precautions. Store in cool, dry and well-ventilated place.

Specific end uses(s)
Not applicable. This product is an intermediate in the production of Pb and Sn metal.

Exposure controls

Organisational measures

Personal Hygiene: Ensure workers follow simple hygiene rules (e.g. do not bite nails and keep them cut short, avoid touching or scratching face with dirty hands or gloves); Ensure workers do not wipe away sweat with hands or arms; Ensure workers use disposable tissues rather than a handkerchief; Prohibit drinking, eating and smoking in production areas, or access to eating and non-production areas in working clothes; Ensure workers wash hands, arms, faces and mouths (but preferably shower) and change into clean clothing before entering eating areas; For high exposure workplaces, separate rooms for cleaning hands, removal of clothes, showers and clean clothes may be necessary; Ensure workers handle dirty working clothes with care; Allow no personal belongings to be taken into production areas, or items that have been used in production areas to be taken home. Ensure general shop cleanliness is maintained by frequent washing/vacuuming. Clean every workplace at the end of every shift.

Blood lead monitoring: Set in place a certified monitoring regime which covers all site activities; Define a policy for submitting workers to regular blood lead monitoring, including increased frequency for workers undertaking high-risk jobs and workers with elevated blood lead levels; Ensure all workers have a blood test prior to working on site. Set an “action level” that is typically 5 µg/dL below the exposure limit deemed to be safe. If the action level is exceeded, appropriate measures are to be taken, to prevent further increases in blood lead. If the safe threshold is exceeded, continue or begin ban on overtime, ensure strict hygiene procedures are followed, undertake detailed inspections to ensure correct use of personal protective equipment, undertake detailed inspections to ensure recommended workplace procedures are followed, move employee to workplace where exposure is expected to be lower or remove from lead environment altogether, further increase blood lead sampling frequency, and continue frequent sampling until results are below the first action level.

Personal Protection Equipment

Respiratory protection: Suitable respiratory protective device recommended recommended if work activity is likely to result in formation of lead fumes, vapours or dust. In case of brief or low level exposure use dust mask or half mask with particle filter P2. Assess the need to wear respiratory protective equipment in production areas. Consider use effective masks accompanied by a compliance policy (ensure proper shaving; ensure workers do not remove RPE in production areas in order to communicate). Where masks are used, employ formal mask cleaning and filter changing strategies.

Hand Protection: Protective gloves. Material of gloves: Neoprene or Leather.

Eye protection: Safety glasses.

Skin protection: Wear protective work clothing. For workers in areas of significant exposure, provide sufficient working clothes to enable daily change into clean clothes. In such cases all work clothing should be cleaned by the employer on a daily basis and is not permitted to leave the work site.

Environmental Protection

One or more of the following measures may if necessary be taken to reduce emissions to water:
• Chemical precipitation: used primarily to remove the metal ions
• Sedimentation
• Filtration: used as final clarification step
• Electrolysis: for low metal concentration
• Reverse osmosis: extensively used for the removal of dissolved metals
• Ion exchange: final cleaning step in the removal of heavy metal from process wastewater

One or more of the following measures may if necessary be taken to reduce emissions to air:
• Electrostatic precipitators using wide electrode spacing: Wet electrostatic precipitators:
• Cyclones, but as primary collector Fabric or bag filters: high efficiency in controlling fine particulate (melting): achieve emission values Membrane filtration techniques can achieve
• Ceramic and metal mesh filters. PM10 particles are removed
• Wet scrubbers

Lead compound removal from treatment works should be at least the minimum default 84% removal used in the CSR. Solid material collected from on-site treatment must be sent for metal recovery or treated as hazardous waste. Waste water treatment sludge must be recycled, incinerated or landfilled and not used as agricultural fertiliser.
