6.6.13.0 Symptoms of exposure

6.6.13.1 Before handling or working with any chemical, the Control Room Engineer, Craft Person or Craft Group Leader and Entrant should check the Material Safety Data Sheet (MSDS) for details of the hazards, instructions for proper handling and appropriate safety precautions.

6.6.13.2 Acid: Burning of eyes, skin, and respiratory tract.

6.6.13.3 Ammonia: Corrosive to body tissues, larger concentrations can be suffocating and extremely irritating to eyes, mucous membranes and lung tissue.

6.6.13.4 Carbon Monoxide (CO): Headache, palpitations, dizziness, nausea, unconsciousness and eventual death may occur if not removed to fresh air.

6.6.13.5 Caustic: Burning of eyes, skin, and respiratory tract.

6.6.13.6 Chlorine: Irritation of throat, eyes, nose and respiratory track with tearing, runny nose, sneezing, coughing, choking and chest pain. Severe breathing difficulties may occur. Pneumonia may result. Severe exposures may be fatal.

6.6.13.7 Diesel: Slight eye irritation, prolong contact will cause skin irritation or dermatitis, avoid ingestion, prolong breathing of vapours, can cause headache, vertigo, anesthetic stupor.

6.6.13.8 Fuel Gas (Methane): High concentrations may cause asphyxiation. No systemic effects, even at 5% concentration in air. Vapours are non-irritating to the nose and throat and is practically harmless to the skin because it is very volatile and evaporates quickly, but may cause some frostbite.

6.6.13.9 Limestone: Irritation of skin, eyes, and nasal passages, congestion of nasal and respiratory passages.

6.6.13.10 Oxygen Deficiency: These indications are for a healthy average person at rest. Factors such as individual health (e.g. fitness level, smoker, obesity) and degree of physical exertion can affect these symptoms and the oxygen levels at which they occur:Oxygen Content Symptoms of acute exposure at atmospheric pressure(% by Volume)

15-19% Decreased ability to perform tasks. May impair coordination and may induce early symptoms in persons with heart, lung, or circulatory problems.

12-15% Breathing increases, especially in exertion. Pulse rate increases. Impaired coordination, perception, and judgment.

10-12% Breathing further increases in rate and depth, poor coordination and judgment, lips slightly blue.

8-10% Mental failure, fainting, unconsciousness, ashen face, blueness of lips, nausea and vomiting.

6-8% Eight minutes, may be fatal in 50 to 100% of cases; 6 minutes, may be fatal in 25 to 50% of cases; 4-5 minutes, recovery with treatment.

4-6% Coma in 40 seconds, followed by convulsions, breathing failure, death.

6.6.13.11 Solvents: Headache, nasal and respiratory irritation, nausea, drowsiness, fatigue, central nervous system depression, convulsions and loss of consciousness.
