Instructions for Handling Carbon-Remover

Fifth Engineer, you are to draw 5 liters of Carbon-Remover from the main 20-liter drum. This chemical is highly irritant, potentially corrosive, and can cause damage if mishandled. You must strictly follow these instructions.

Part (a)

Precautions to be Taken While Handling

The primary goal is to prevent any contact with the chemical and avoid inhaling its fumes.

  1. Review Safety Data Sheet (SDS): Always read the SDS for the specific carbon-remover first to understand its exact hazards (e.g., flammability, toxicity, corrosiveness).
  2. Wear Full Personal Protective Equipment (PPE): Before starting, don the following:
    • Chemical-resistant gloves (ensure they are intact).
    • Safety goggles or a full face shield.
    • Coveralls (long-sleeved).
    • A suitable respirator mask if the working area is poorly ventilated.
  3. Ensure Proper Ventilation: Only handle the chemical in a well-ventilated area. Never work in a confined space. Avoid inhaling the chemical fumes at all times.
  4. Check Containers:
    • Confirm the 20-liter drum is labeled correctly and is not leaking.
    • Ensure the receiving container for the 5 liters is clean, dry, clearly labeled, and made of a compatible material (e.g., appropriate plastic or steel). NEVER use a food or drink container.
  5. Handling Procedure:
    • Avoid splashing when dispensing. Use a dedicated pump or dispensing tool if available to control the flow.
    • Do not touch your face, eyes, or mouth during the transfer.
    • Avoid introducing any open flame or high heat source into the working area, as some carbon-remover variants are flammable.
  6. Spillage and Clean-up:
    • If any spillage occurs, immediately notify a senior engineer.
    • Use appropriate absorbent materials (like sand or universal binders) for clean-up. Do not rinse into drains.
    • Ensure proper environmental disposal methods are followed for unused chemical, empty drums, and all spill cleanup materials.

(b) Measures to be Taken if:

(i) Chemical Contacts the Skin

  1. Immediately remove all contaminated clothing.
  2. Rinse the affected area thoroughly with running water for at least 15 minutes.
  3. Wash gently with mild soap and water — do not scrub harshly.
  4. If irritation, redness, or rash occurs, or if a large area is affected, seek medical attention promptly.
  5. Provide the chemical label or SDS to medical personnel.
  6. Wash contaminated clothing before reuse; discard heavily contaminated garments or shoes.
  7. Reinforce hygiene — wash hands thoroughly before eating, drinking, or touching the face.

(ii) Chemical Contacts the Eyes

  1. Immediately flush the eyes with copious running water for at least 15 minutes, keeping eyelids open.
  2. Use an eyewash station if available.
  3. Remove contact lenses carefully during flushing, if easy to do.
  4. Do not rub the eyes, as this can aggravate injury.
  5. Seek immediate medical attention, even if irritation subsides — chemical exposure may cause serious or permanent damage.
  6. Provide the SDS and container label to medical staff for accurate treatment.
