Chemical Hazard
Potential to cause harm
Classification:
- Aromatic & Aliphatic
- Target organ dysfunction
- Toxidromic approach

• All have occupations
• All Occupations have hazards
• All hazards are preventable and controllable
• Rarely treatable
• Individual & productivity suffers
• Love thy Occupation
• Where are those occupation ?

Specific exposure group - Awareness
• Unknown Hazard – Unknown Workers
- Pesticides, antibiotics , heavy metals
• Known Hazard – Unknown Workers
- Induction and Training
• Known Hazard – Known Workers
- Monitoring
• Unknown Hazard – Unknown Workers
- Hazard interaction, Explosive, Inflammable
Chemical Hazard life cycle Continues …
Paradox
• Knowledge
• Training
• Right PPE for the right job – Appropriate PPE usage
Hazard ?
10
Chemical Handling
Transport Emergency (TREM) Card
Specialized Training
Material Safety Data Sheet (MSDS)
- Vernacular language
- PEP talks, Job Safety Analysis (JSA), Hazard Identification & Risk Analysis
(HIRA)
Appropriate training & PPE usage
Storage of Chemicals
- Proper labeling (Pictorial) / Standard Operating Procedure (SOP)
Emergency Measures
- Chemical Inventory and Antidotes

Pain Abdomen
Hgic Pancreatitis
Caecoplasty
Appendisectomy

Metal Fume Fever

Porphyria – Welding fumes
• Disease (or) Drug Induced / Partly Treated
Early Parkinson’s Disease
• Anti depressant
• Manganese, Copper
Mercury
• Leprosy
Ataxia
• Acoustic Neuroma
Chemical Hazard

18
Acoustic Neuroma
History of exposure alone is inadequate for diagnosing an
Occupational Disease
Anaemia
• Asymptomatic Healthy Male Scientist (R&D)
• Ignorant Bottom Loss
• Hidden Hypo Thyroid
Absence of an evidence of Disease is not an evidence for its absence

Toxicology concerns the potential of chemicals to produce
adverse effects in the body.
“It is the dose that makes the poison”
The hazard of a given substance is related to
A. its absolute toxicity
B. its physico-chemical properties
C. circumstances of use-concentration,
D. length of exposure,
E. body area exposed.
F. Bio-variability
Toxicology
24
Endocrine System
Shift Work ----- Circadian Dysrhythmia Drugs ----- Hormones, Pharmaceuticals
• Anaesthetic gas
• Lead, Mercury, Arsenic, Carbon Disulfide, Cadmium
• Radiation, Heat
• Fertility, Torch, Menstrul Disorder, Con. Malformations,
Low Birth Weight
Asbestos, Carbon-Monoxide – Cross the Placenta
25
Training at medical school - Orientation
- Life is a learning process; Learning is a life long process
Cause ? effect ? Why Why analysis ?
- History of exposure to chemicals alone is inadequate
Bio variability matters
- Evidence beyond doubt
Expect the Unexpected
Learnings

“ And in the end if that the work man
shall live to enjoy the fruits of his
labour, that his mother shall have
the comfort of his arm in her age,
that his wife shall not be untimely
a widow, that his children shall
have a father and that cripples
and hopeless wrecks who were
once strong men shall no longer
be the bye-products of industry”
Prayer
