[Exposure= frequency X Intensity X Time]

ERGONOMETRY

Definition- Interaction between human and design

Types (CEO): Cognitive (E), Ergonometric/Physical (E), Organization (E),

Relevance (3T): Technology, Time, Task

Task: Worker, Job Design, Environment, Tools, Organization

Effect: (W.E.I.R.D)- Wasting, Error, Injury, Reduced Quality, Damaging

Risk (F=P.V/R)- Force, Posture, Vibration, Repetition

Risk Management/Intervention

(H.A.D.I.R)- Hazard Identification, Assessing risk, Decide the Control, Implement the Control, Review Monitoring.

Industrial Hygiene- Anticipation, Recognition, Evaluation, Control

CHEMICAL

Definition- Interaction between human and toxic chemical

Types: Dust, Vapor, Fumes, Mist, Gaseous

(Dust is solid in room temperature, Vapor is Liquid in room temperature, Fumes is Metallic reaction to heat, Mist is chemical reaction with water or heat, gaseous is gas in room temperature)

Factor/Risk: Solubility, Particle sice <5um

Classification of Organic Chemical: Mutagenic (acridine), Carcinogenic (Benzene), Teratogenic (Organic sol.)

Effect: Pneumoconiosis- Asbestos, Silicon, Beryl

Risk Management:

(H.A.D.I.R)- Hazard Identification, Assessing risk, Decide the Control, Implement the Control, Review Monitoring.

Industrial Hygiene-A.R.E.C

Additional Evaluation- ORIGinalS:

Surveillance: Environment (Area/Personal) M, Biological (M), Health (S)

Sampling: TLV-TWA or C

Additional Control - Safety Data Sheet, Labels

BIOLOGICAL

Definition- Interaction between human and living organism/product

Transmission Chain: Reservoir-> Portal Exit-> Mode of Transmission-> Portal of Entry-> Potential Host

Types of Agent: Infectious Agent, Plant, Animal

Types of Outcome: Infectious, Allergic, Poisonous

WHO Classification: (in Group 1 even immune-compromised might effected)

Group 1- Unlikely to Human Disease (eg: Yeast)
Group 2- Unlikely to Spread (eg: Leigonella)
Group 3- Effective Prophylaxis (eg: Tuberculosis)
Group 4- All the Above failed (HSP) (eg: E-Bola)

Risk Management:

(H.A.D.I.R)- Hazard Identification, Assessing risk, Decide the Control, Implement the Control, Review Monitoring.

Industrial Hygiene- Anticipation, Recognition, Evaluation, Control

Anticipation: LITERATURE
Recognition: DATA (Medical chart, Safety Data Sheet, Work Environment Measure)
Evaluation: From (ORIGinalS^)- Observation, Report/Record, Interview, General Meeting, Surveillance/Sampling
Control Hierarchy in Industrial Hygiene: (BAD ENSUEL)- Elimination, Substitution, Engineering, Administration, Behavioral
