Module 6 Flashcards
Aims of Occupational Health
- Promotion and maintenance of the physical, mental and social well-being workers.
- Prevention of illness.
- Protection of workers from risk at work.
- Placement and maintenance of workers in an occupational environment
appropriate to his capacity.
measure in (hertz) cycles per second.
Frequency
intensity of the sound, measured in Decibel (dB)
Loudness
continuous, intermittent, burst, waxing/waning
Duration
Adverse Health Effects of Noise
(Acute Effects)
a. Acoustic trauma (explosion, gunshot)
b. Temporary Threshold shift (disco)
c. Poor communication
d. Increase in blood pressure and stress
Chronic or long-term effects (Noise)
a. Permanent threshold shift (noise included hearing loss)
b. Hypertension and stress
c. Psychosomatic effects
Control of Noise Problems
(Engineering Methods)
a. Purchase of new equipment
b. Preventive maintenance
c. Isolation/damping
Administrative Control (Noise)
Job rotation
Exposure settings (Heat Stress)
- High Humidity
*Poor ventilation
*Multiple Heat Sources - High Temperature
Acute Health Effects of Heat
- prickly heat
- heat fatigue
- heat cramps
- heat exhaustion
- heat stroke
Control of Heat Problems
(Engineering control)
a. Ventilation
b. Water Sources
Administration control (Heat Stress)
a. Job rotation/breaks
b. Cotton clothes, multiple changes
Acute Health Effects of Cold
*hypothermia
*frostbite
*trench foot
Chronic Health Effects of Cold
*bradycardia
*skin scaling
*callous formation
Health Effects of Vibration
● Inflammation (wrist, elbow, shoulder)
● Carpal tunnel syndrome
● Fatigue
Prevention and Treatment (Vibration)
Tool Redesign
● Maintenance of equipment/tools
● Isolation
● Gloves, dampers
Importance of Illumination
● Clerical work
● Fine movements work
Subsequent accidents that may happen (Illumination)
● Leaning close to machinery
● Loose clothing gets caught
● Loss of leg balance
● Loss of arm support
● Inhale particulate matter
Acute Effect of Illumination
● Eye strain
Control and Prevention of Illumination
o Propper lighting/ illumination in the workplace
This is the atmospheric force that is constantly applied on the blood
Pressure
Acute Effects of Pressure
- Fatigue
- Headache
- Apprehension
- Tremors
- Dizziness
- Narcosis
- Death
- Convulsions
- Excitability
- Incoordination
Chronic Effects of Pressure
- Fatigue
- Apprehension
- Anemia
- Hypoxia
- Hypercalcemia
- Muscle Atony
- Muscle Atrophy
- Bone wasting
Control Methods (Pressure)
- Training (Pre-events)
- Exercise (During)
- Rehabilitation (Post-events)
- Medications
- Medical monitoring
