Historical background l.jpg
HISTORICAL BACKGROUND

  • Case of “RAYLAND FLETCHER”

  • Judgment by BRITISH COURT known as “PRINCIPLE OF RESTRICTED LIABILITY”

  • If any disaster occurs, PERSON will be responsible except

  • ACT OF GOD (Natural Disaster)

  • NOT DUE TO NEGLIGENCE

  • IF NEIGHBOUR AGREE

  • Case of BHOPAL GAS LEAK (1984)

  • Judgment by Hon’ble Supreme Court by Chief Justice Shri.P.N.Bhagwati

  • “PRINCIPLE OF ABSOLUTE LIABILITY”

  • Leads to enactment of EPA and Public Liability Insurance Act


Definations l.jpg
DEFINATIONS

  • Hazard:

    Something that has the potential to cause human injury, ill health and/or damage to

    property (machinery and equipment) or to the environment.

  • Risk:

    The probability (likelihood) of harm or damage occurring from exposure to a hazard, and the likely consequences of that harm or damage


Hazard management process l.jpg
HAZARD MANAGEMENT PROCESS

  • Identify the hazards

  • Assess the risks

  • Evaluate risks

  • Control the risks

  • Monitor and Review


Identifying hazards l.jpg
IDENTIFYING HAZARDS

  • Safety Hazards

  • Health Hazards

  • Environment Hazards

    To identify hazards, we need to understands that hazards can be

  • Obvious

  • Hidden or

  • Developing


Assess the risk l.jpg
ASSESS THE RISK

  • WHAT IS RISK????

  • Injury

  • Illness

  • Damage

  • Productivity Loss


Factors l.jpg
FACTORS

  • Likelihood - What is the probability of it happening?

  • Degree of Exposure - How often would I be exposed?

  • Consequence - If it occurs, what will happen?


Risk level l.jpg
RISK LEVEL

  • Likelihood x Consequence (Severity)

  • Hazards can be ranked with a high to low risk


Likelyhood exposure l.jpg
LIKELYHOOD & EXPOSURE

  • What is the likelihood of the hazard leading to an incident and possibly injury/damage?

    Degree of Exposure

  • How long?

  • How often?

    are you or others exposed to the hazardous situation ?


What to consider l.jpg
WHAT TO CONSIDER?

  • the number of times tasks are undertaken which could result in an incident;

  • the number of people performing the

    task(s); and

  • the likelihood of the incident occurring while the task is being performed


Types of hazard l.jpg
TYPES OF HAZARD

  • FLOODS

  • CYCLONE

  • DRAUGHT

  • EARTHQUAKE

  • SEA LEVEL RISE

  • CHEMICAL SPILLAGE/LEAKAGE

  • OIL SPILL

  • INDUSTRIAL ACCIDENTS


Risk assesment methedology l.jpg
RISK ASSESMENT METHEDOLOGY

  • Vulnerability Assessment

  • Institutional Appraisal

  • Establishment of Risk Exposure

  • Possible Mitigative Measures

  • Information Dissemination thro’

    Networking/Right To Information Act


Role of regulator l.jpg
ROLE OF REGULATOR

  • SYSTEMATIC APPROACH

    Formal System v/s Informal System

    Technology v/s Human Attitude

  • SHE (Safety, Health and Environment)

  • On Site/Off Site Emergency Plan

  • Documentation and Verification


Case study fire incident at common haz waste incinerator facility l.jpg
CASE STUDY:FIRE INCIDENT AT COMMON HAZ WASTE INCINERATOR FACILITY

  • Fire took place at waste storage area (shed:7) at 18.10 hrs. on April,3rd 2008

  • Message received by Authorities at 18.30 hrs

  • First Firetender reached at 18.30 hrs

  • GPCB with Toxicity monitoring team reached at 19.15 hrs

  • DPMC/GNFC/ONGC/IPCL/GSFC requested for assistance

  • 39 Firetender reached at site

  • Foam/DCP powder used for extinguishing

  • Fire brought under control at 21.00 hrs

  • Fire totally extinguished at 5.30 hrs on morning


Activities undertaken l.jpg
ACTIVITIES UNDERTAKEN FACILITY

  • Drains blocked to contain contaminated hydrant water

  • 1380 KL contaminated hydrant water sent to CETP for treatment

  • 211 MT of waste collected from shed:7 and incinerated

  • Contaminated water (aqueous waste) @ 99 MT collected from collection pit/drains and incinerated

  • District Collector directed DHO for continuous monitoring for health check up of people of surrounding village

  • GPCB/AEPS/BEIL team monitored site & surrounding areas/villages downwind collecting water/soil samples

  • Continuous ambient air monitoring in villages/area downwind


Cause of incident l.jpg
CAUSE OF INCIDENT FACILITY

  • Pyropheric reaction that may have occurred due to presence of Iron Sulfide either present in waste/or produced on account of chemical reaction in steel drum containing sulfide

  • Some reactive, unstable and Pyropheric wastes may get auto ignited on contact with Oxygen

  • Excess storage of incinerable waste without considering compatibility of waste stored

  • In sufficient space for removal of leaked drums

  • Insufficient fire hydrant system


Action taken l.jpg
ACTION TAKEN FACILITY

  • Directions under Water Act-1974, Air Act-1981 ad EPA-1986 issued by GPCB

  • Prosecution in the Court of Law under EPA-1986

  • Direction of Closure issued by CPCB

  • CPCB constituted a committee to develop guideline for “limiting storage time for storage of incinerable waste in common facility”

  • Guideline developed and put up on CPCB website


Lesson learnt l.jpg
LESSON LEARNT FACILITY

  • Safety study carried out by External Expert Agency

  • New fire hydrant line covering all storage sheds put up

  • Construction of peripheral road around storage shades

  • Construction of additional three storage sheds and reconstruction of storage shed:7 after clean up

  • All storage sheds provided with smoke & heat detector system linked with peripheral water sprinkling system

  • Re arrangement of waste stored based on its compatibility

  • Alternative arrangement for incineration of waste at other common facilities at Baroda/Surat/Vapi

  • Local Crisis Group (LCG) for off-site mock drill

  • Approached NEERI to carry out study on “Post Impact of accident on Environment, Health & Property covering Safety Aspects”
