Q

TYPES OF MONITORING

A

Ambient Monitoring
Health Surveillance

25
Biological Monitoring:
Exposure Monitoring Effect Monitoring
26
total workplace atmospheric contents
Ambient Monitoring
27
based on analysis of complaints from workers, or annual summary of Clinic cases, you establish epidemiological relationships that give evidence to harmful substances in the workplace.
Health Surveillance
28
detect presence of substances in the worker even in low quantities; possibly no health effects seen yet
Exposure Monitoring
29
you are detecting the presence of materials in the workers through the complaints or visible physical changes in the workers health ( the damage has been done)
Effect Monitoring
30
BASIC STEPS
Review of workplace condition Exposure measurements Health monitoring
31
GENERAL CONSIDERATIONS
WHERE to sample WHEN to sample WHOM to sample HOW MANY samples to take HOW LONG to sample
32
Samples should be collected at or near the workers breathing zone or near the vicinity of the source.
WHERE to sample
33
Samples should be collected
WHEN to sample
34
WHEN to sample
.during each shift .pre- and post-shift .single .repeated
35
Sampling must be done to the most highly exposed employee with consideration of the
WHOM to sample
36
WHOM to sample
.ventilation booths .air supply index .open doors and windows .size and shape of the work area
37
It depends on the purpose of the sampling. Sufficient quantity of the sample must be collected to determine minute amounts of the air contaminants. The sensitivity, accuracy, and reproducibility of the instruments must also be considered.
HOW MANY samples to take
38
sampling usually takes a complete cycle of operation, however, for air sampling, air-borne contaminants of toxic substances may vary from each shift due to
HOW LONG to sample
39
HOW LONG to sample
.air currents within a room .process variations .change in work practice by an operator .variation in emission rate of a contaminant
40
FREQUENCY OF MONITORING
Toxicity Invasiveness of Test Expense Availability Pre- and Post-shift
41
handling of moving parts that are automated or manually operated
MACHINE SAFEGUARDING / MECHANICAL HAZARDS
42
MACHINE SAFEGUARDING / MECHANICAL HAZARDS
1. Point of operation 2. Power transmission apparatus 3. Other moving parts
43
The point in the machine where work is performed on the material.
POINT OF OPERATION Examples: Cutting, shaping, boring or forming stock
44
All components of the mechanical system which transmit energy to the part of the machine performing the work.
POWER TRANSMISSION APPARATUS Examples: Flywheels, pulleys, belts, couplings, gears.
45
All parts of the machine which moves while the machine is working.
OTHER MOVING PARTS Examples: Reciprocating, rotating, and transverse moving parts
46
Static protective device that prevents access to the moving parts:
MACHINE GUARDING (or machine guard) Grills, screens, covers, hoods Location and distance Gates, perimeter fences Windows, shutters
47
 Not grounded properly (electrical)  Failure of high-pressure system (pneumatic machines)  Noise (unwanted sound)  Potentially harmful substances (cutting fluids, coolants
NON-MECHANICAL HAZARDS
48
The passage of electrical current through your body is felt as shock Even if shock doesn’t cause direct injury, reflex action by your muscles may cause falls or sudden moves into other hazards.
ELECTRICAL EMERGENCIES
49
The degree of injury from shock depends on the:
1. The amount of current, or amperage 2. The length of time exposed 3. The path of electrical current takes
50
Employees who should know about LO/TO
Authorized employee Affected employee Other employees
51
a person who locks out or tags our machinery or equipment in order to service or maintain it.
Authorized employee
52
an employee whose work involves use or operation of equipment under lockout/tag out or who works in the area where service is being performed.
Affected employee
53
those who work near machinery that is under subject to LO/TO
Other employees
54
7 STEPS TO LOCKOUT / TAGOUT
1. Prepare for Shutdown– know the equipment /its energy source before working 2. Notify employees 3. Shutdown equipment 4. Isolate the equipment 5. Apply the Lock and Tag 6. Release stored energy 7. Verify that the power is OFF
55
3 STEPS TO REMOVAL and RE-ENERGIZING a system
1. Remove tools / replace guards 2. Check for employees 3. Remove the Lockout/Tag out 4. Notify Affected employees 5. Restore energy to the equipment
56
- is sometimes described as “fitting the job to the person, rather than the person to the job”. -The _approach, taking into account a range of relevant factors including the nature of the task, the load, the working environment, and individual capability - It is the Study of people’s efficiency in their working environment.
Ergonomics
57
FACTS TO BE CONSIDERED:
Sprains and strains Poor posture and excessive repetition
58
When moving things from high places:
1. Use a stool or platform 2. Push the load to check how heavy and stable it is 3. See if you can break the load into smaller pieces 4. Get help if you think you might need it
