HIRARC

MADE UP FROM 3 ACTIVITIES THAT CONSIST OF HAZARD IDENTIFICATION, RISK ASSESMENT AND RISK CONTROL

HAZARD IDENTIFICATION• RECOGNISING OF THINGS WHICH MAY CAUSE INJURY OR

HARM TO A PERSON

RISK ASSESMENT• LOOKING AT THE POSSIBILITY OF INJURY OR HARM OCCURING

TO A PERSON IF EXPOSED TO A HAZARD

RISK CONTROL• INTRODUCTION OF MEASURES WHICH WILL ELIMINATE OR

REDUCE THE RISK OF A PERSON BEING EXPOSED TO A HAZARD

BEFORE THE PROCESS OF IDENTIFIYING ANY HAZARDS

HAZARD – ANYTHING THAT CAN CAUSE HARM

RISK – A PROBABILITY OF HARM ACTUALLY BEING DONE

DANGER – THE RELATIVE EXPOSURE TO A HAZARD

PROCESS OF HIRARC• 1- CLASSIFY WORK ACTIVITIES

• 2- IDENTIFY HAZARDS

• 3- CONDUCT RISK ASSESMENT-ANALYZE AND ESTIMATE RISK FROM EACH HAZARD BY CALCULATING OR ESTIMATING LIKELIHOOD OF OCCURANCE AND SEVERITY OF HAZARD

• 4- DECIDE IF RISK IS TOLERABLE AND APPLY CONTROL MEASURES (IF NECESSARY)

SOURCE OF HAZARDS

• HUMAN BEING- DANGOURES ACT• MACHINES- APPLIANCES,PROCESS FLOW• MATERIAL- LINE CHEMICALS AND SOLVENT• PROCESS- MAY A PROCESS IS CONDUCTED• SURROUNDING- SURROUNDING WORK

ENVIRONMENT RADIATION,VIBRATION,NOISE

HAZARD

CONDITION WITH THE POTENTIAL OF CAUSING INJURY, DISEASES, DAMAGE TO EQUIPMENT,

LOST OF MATERIAL AND DAMAGE TO THE ENVIRONMENT

IDENTIFICATION TYPES OF HAZARDSPHYSICAL HAZARDS - HEIGHT, FORCE, NOISE, VIBRATION,

LIGHTING- NOISE - IT CAN CAUSE HEARING LOSS

- FACTORS – INTENSITY OF THE NOISE- FREQUENCY

- CONTROL NOISE – CHANGE WITH OTHER PROCESS OR EQUIPMENT

- VIBRATION- RESULT IN TISSUE DAMAGE

- CONTROL VIBRATION – USE OF VIBRATION ISOLATOR- SELECT EQUIPMENT THAT PRODUCES

LESS VIBRATION

CHEMICAL HAZARDS GAS , LIQUID,FUMER,MIST,DUSTASBESTOS - CAUSE LUNG CANCER

- DEVELOPS 20-40 YEARS OF EXPOSURE

- TOXIC EFFECT- IRRITERATIONS- CANCER

- EFFECT IN 20-30 YEARS- SOURCES – BENZENE (LEUKIMEA)- VYNIL CHLORIDE(LIVER CANCER)

- ROULES OF ENTRY TOXIC- RESPIRATORY- SKIN AND EYE CONTACT- MOUTH- INJECTION

- FACTOR AFFECTING TOXIC EFFECT- RELATED TO THE AGENT

- CHEMICAL COMPOSTION- PHYSICAL PROPERTIES

- EXPOSURE SITUATION- DOSE: HOW MUCH HOW LONG

- INDIVIDUALS- INDIVIDUALS DIFFERENCE : GENETIC STATUS AND

ALERGIC STATUS- AGE

BIOLOGICAL HAZARDSLIVING ORGASM (BACTERIA , VIRUS)

ELECTRICAL HAZARDSCURRENT , VOLTAGE

RADIATION HAZARDSUV LIGHT, LASER

PSYCHOLOGICAL HAZARDSWORKPLACE, SPACE, ORGANIZATIONANL CULTURE, STRESS

CONTROLLING THE RISK- ELIMINATING THE HAZARD- MINIMIZING- CONTROLLING THE HAZARDS

ETHICS- PRINCIPLE OF GOOD AND BAD BEHAVIOUR GOVERNING WHAT IS RIGHT

AND WRONG CONDUCT

CODE OF ETHICS (WHY WE NEED)

- EXPRESS THE RIGHTS, DUTIES AND OBLIGATIONS OF THE MEMBER OF THE PROFESSION

- PROVIDES FRAMEWORK FOR ARRIVING AT GOOD ETICHAL CHOICES- TO BE REFLECTIONS OF THE MORALLY PERMISSIBLE STANDARDS OF

CONDUCT WHICH MEMBERS OF A GROUP MAKE BINDING UPON THEMSELVES

- DEFINES YOUR RESPONSIBILITIES TO SOCIETY AND THE ENVIRONMENT , YOUR EMPLOYER OR CLIENT AND YOUR FELLOW ENGINEERS
