MOD 6 Flashcards
is anything that produces adverse effects on anyone.Examples of
_____ are slippery floors, falling objects, chemicals and many more.
Hazards
These are very common in companies that utilize oil, water or any liquidin the
production process and in the construction industry where there are a lot of falling debris, like small pieces of wood, nails, and hand tools
Direct hazards
Types Physical hazards
Noise, Extreme Temperatures, Radiation, Extreme Pressure, and Vibration
extreme heat which can cause _______
heat stroke
extreme cold which can cause _______
hypothermia
- from the sun can be shielded by paper
Ultraviolet (UV) light or alpha particle
Radiation also has two types:
the ionizing radiation and the non- ionizing type
can penetrate concrete. This can be shielded by using lead like in the x-ray
room which is made up of sheeted lead in-between concrete to prevent outside
exposure
Gamma ray
can penetrate paper but not concrete.
Beta particle
radio waves, electric waves and infrared rays. An example is the welding process which
produces infrared rays that can damage the skin.
Non-ionizing radiation
These are pressures beyond the allowable levels needed by the
human body. Examples of workers
exposed to extreme pressure are those involved in excavation work, scuba diving, and
piloting airplanes.
Extreme Pressure
is dangerous because it cannot be detected by the five senses but it destroys
the cells and tissues of living organisms, and has long-term effects.
radiation
These are hazards caused by viruses, fungi and bacteria
Biological Hazards
These are substances in solid, liquid or gaseous forms known to cause
poison, fire, explosion or ill effects to health. Examples include gases, fumes, vapor, mist
and dust. These are airborne particles or airborne toxic elements that evaporate in the air
and can cause irritation, discomfort and even death.
Chemical Hazards
These are caused by improper posture or postural stress.
Ergonomic Hazards
There are three methods in controlling hazards
engineering, administrative and PPE
his is the application of engineering technology to control
hazards. An example is machine guarding which prevent anyone from coming in contact with
moving parts of a machine during the operation. Other examples are installation of safety devices
like emergency stop, limit, grab-wire and photo electric switches. These prevent accidents in case
of improper work practices.
Engineering method
– this aims to minimize the exposure of humans to workplace
hazards and employs administrative approaches such as rotation and shifting
Administrative method
these are considered as the last line of defense. These devices provide limited
protection to the ones using them.
PPE
The policy should state the need for the use of PPE. It may also contain exceptions or limitations
on the use of PPE. These are:
Selection of Proper Equipment, Proper Training, Maintenance Program, and Enforcement.
The following are the functions and uses of PPE.
Head Protection, Eye Protection, Face Shields, Ear Protection, Respiratory Protection, Hand and Arm Protection, Foot and Leg Protection, Fall Protection, Torso/ Full Body Protection
Hazards under respiratory protection
o Mists or Vapors
o Gases
o Smoke
o Fumes
o Particulates or dust
o Insufficient oxygen supply
Types of respirators are divided into two categories
Air purifying respirators and Air supplying devices
screen out dust, fog, fume, mist spray or
smoke. Such filters need to be replaced at frequent intervals.
Particulate respirators or mechanical filters
