HAZARDS



is a situation that poses a level of threatto life, health, property, or environment.



Proportional Contribution of

Acts and Conditions



Classification of HazardousConditions



1. Bio-physical hazards

Poor housekeeping

Noise

Poor lighting

Special Hazards (Radiation and extreme

Temperature)



3. Electrical Hazards

Wiring

Grounding

Power panels

Outlets and switches



4. Chemical Hazards

Human contact (injury/illness)

Property damage (fire/explosion)

Environmental contamination(air/ground/water)



1. Fundamental Approach

it consist of the study of all possiblehazards that could exist. It is both

quantitatively and qualitatively. First,ensuring that all are recognized thencalculating the probability contributed byeach then getting the overall potential

occurrence. This is being done by newlyintroduce products or project that mightaffect the consuming public.



2. Technical or Loss Control

Approach

it involves the thorough recording andstudy of as many accidents as possible toidentify and eliminate the hazards thatcaused them.



What is Hazard AnalysisAssessment?

Hazard analysis is an organized and orderlyprocess used to acquire specific information pertinent

to a given work system. In management decisions,hazard analysis as information help things work out forthe right reasons. The method forces thoseconducting the analysis to ask the right questions and

it also helps to answer those questions. By locatingthose hazards that are the most probable and/orhave the severest consequences, hazard analysisproduce information essential in establishing effectivecontrol measures.



Purpose of Hazard Analysis It can uncover hazards that have been

overlooked in the original design, mock-up, or set-up of a particular process, operation or task.

It can locate hazards developed after a particularprocess, operation or task instituted.

It can determine the essential factors in andrequirements for specific job processes, operationsand tasks. It can indicate what qualifications areprerequisites to safe and productive workperformance.



It can indicate need for modifying processes,operations or tasks.

It can identify situational hazards in the facilities,equipment, tools, materials and operational events.

It can identify human factors responsible foraccidents situations.

It can identify exposure factors that contribute toinjury and illness.

It can identify physical factors that contribute toaccident situations.

It can determine appropriate monitoring methodsand maintenance standards needed for safety.



Formal Methods of Hazard Analysis



Inductive Method

uses observable data to predict what canhappen. It postulates how thecomponent parts of a system willcontribute to the success or failure of thesystem as a whole. The inductive method

forms the basis for such analysis as ‘failuremode and effect analysis’ (FMEA) and‘operations hazard analysis” (OHA).



PERSONAL DEFECTS

orJOB FACTORS



Human Factor in Accident

Between inherent factors and temporary

factors resulting from stresses, training andetc.

Between physical and mental orphysiological

Between factors of age and sex Learning curves or the rate and ability to

learn.
