what is RIDDOR (Reporting Of Injuries, Diseases And Dangerous Occurrences Regulations 1995)

Introduction

Under RIDDOR, employers and other responsible people who have control over employees and work premises have certain responsibilities.
If any of the following events occur at work, employers and other responsible people must report the incident to the relevant enforcing authority.

What has to be reported?

If incidents involving staff, patients, contractors and visitors fall within these criteria, they should be reported under RIDDOR.
• Deaths
• Major injuries
• Accidents resulting in over three-day injuries
• Diseases
• Dangerous occurrences
• Gas incidents

Death or major injury

Line managers, the nominated person, safety supervisor and health and safety services must be informed immediately so they can report to the HSE without delay.
Health and safety services will report the accident to the HSE by telephone and complete the appropriate form within 10 days.

Death

If there is an accident connected with work and:
• Your employee, or a self-employed person working on your premises is killed or suffers a major injury (including as a result of physical violence); or
• A member of the public (including students) is killed or taken to hospital.
Major injuries
• Fracture other than fingers, thumbs or toes
• Amputation
• Dislocation of the shoulder, hip, knee or spine
• Loss of sight (temporary or permanent)
• Chemical or hot metal burn to the eye or any penetrating injury to the eye
• Injury resulting from an electric shock or electrical burn leading to unconsciousness, requiring resuscitation or admittance to hospital for more than 24 hours
• Any other injury leading to hypothermia, heat-induced illness or unconsciousness; or requiring resuscitation or admittance to hospital for more than 24 hours
• Unconsciousness caused by asphyxia or exposure to harmful substance or biological agent
• Acute illness requiring medical treatment or loss of consciousness, arising from absorption of any substance by inhalation, ingestion or through the skin
• Acute illness requiring medical treatment where there is reason to believe it resulted from exposure to a biological agent or its toxins or infected material.


Accidents resulting in over three-day injuries

An over three-day injury is one which is not 'major' but results in the injured person being away from work OR unable to do their full range of their normal duties for more than three days.
If there is an accident connected with work (including an act of physical violence) and a person working on your premises suffers an over-three-day injury, you must report it to the enforcing authority within ten days. This applies if the person is an employee or self-employed.
Disease

If a doctor notifies you that your employee suffers from a reportable work-related disease then you must report it to the occupational health service, who will notify the enforcing authority. Reportable diseases include:
• Certain poisonings
• Some skin diseases such as occupational dermatitis, skin cancer, chrome ulcer, oil folliculitis/acne
• Lung diseases including: occupational asthma, farmer's lung, pneumoconiosis, asbestosis, mesothelioma
• Infections such as: leptospirosis; hepatitis; tuberculosis; anthrax; legionellosis and tetanus
• Other conditions such as occupational cancer; certain musculoskeletal disorders; decompression illness and hand-arm vibration syndrome.


The occupational disease flowchart shows the procedures once a disease is identified.

Dangerous occurrence

If an incident does not result in a reportable injury, but clearly could have done, then it may be a dangerous occurrence and must be reported immediately (by telephone or completing a form on our website).
Reportable dangerous occurrences include:
• Collapse, overturning or failure of load-bearing parts of lifts and lifting equipment
• Explosion, collapse or bursting of any closed vessel or associated pipe work
• Failure of any freight container in any of its load-bearing parts
• Plant or equipment coming into contact with overhead power lines
• Electrical short circuit or overload causing fire or explosion
• Any unintentional explosion, misfire, failure of demolition to cause the intended collapse, projection of material beyond a site boundary, injury caused by an explosion
• Accidental release of a biological agent likely to cause severe human illness;
• Failure of industrial radiography or irradiation equipment to de-energise or return to its safe position after the intended exposure period
• Malfunction of breathing apparatus while in use or during testing immediately before use
• Failure or endangering of diving equipment, the trapping of a diver, an explosion near a diver, or an uncontrolled ascent
• Collapse or partial collapse of a scaffold over five metres high, or erected near water where there could be a risk of drowning after a fall
• Unintended collision of a train with any vehicle
• Dangerous occurrence at a well (other than a water well)
• Dangerous occurrence at a pipeline;
• Failure of any load-bearing fairground equipment, or derailment or unintended collision of cars or trains
• A road tanker carrying a dangerous substance overturns, suffers serious damage, catches fire of the substance is released
• A dangerous substance being conveyed by road is involved in a fire or released.

How caffeine affects your body and brain

Coffee, tea, and cola are just three substances many of us look to for our daily caffeine fix. But what exactly is happening to our brain and body when we take in this colorless, odorless, tasteless drug?

From our bloodstream to our brain, caffeine affects multiple areas of our body in different ways that ultimately leads to more than just a boost in wake-fullness: Caffeine can also improve our mood, enhance focus, and reduce appetite.

Here's a graphic that shows what caffeine is doing in our bodies hours after consumption.

What is difference between NEBOSH, OSHA and IOSH?

Many students & professional ask us the difference between IOSH , NEBOSH & OSHA which are widely demanded for jobs in HSE field .

Choosing certification depends on many factors . your current financial status , Experience & Education level , your commitment to career development & largely , weather you are serious to take HSE as full time career or just wish to add flavor to your engineering degree & shaping your safety skills . if the answer is later , then i will suggest you should start with IOSH Managing safely program . this innovative 24 taught hours program will give you better insight on how to manage your job safely using scientific techniques of Risk Assessment & control 





NEBOSH((National Examination Board in Occupational Safety and Health)

NEBOSH IGC is primarily for those who wish to take HSE as full time career irrespective of their degree background . if you wish to see yourself working on positions like HSE Engineer , HSE officer etc , then NEBOSH IGC is an ideal choice . bear in mind that this course requires significant amount of Money , Time & efforts compared to IOSH Managing Safely . NEBOSH denotes for National Examination Board on safety & Health which is a UK based Examination body who confer Certificates & Diploma in Health & safety to both British & overseas aspirants .whereas IOSH is institution of safety & health of UK , world's largest professional & research based membership body of safety professionals who research & give recommendations to statutory bodies of UK on matters pertaining to health & safety at workplace.

NEBOSH IGC Question and Answers PART 1

OSHA(Occupational safety & health administration)

OSHA is neither course nor certification . OSHA is regulatory & compliance body of health & safety in America , stands for Occupational safety & health administration which offer10 hours &30 hours awareness classes only for workers on OSHA regulations & standards related to different jobs at workplace for example work at height & excavations . after this training , OSHA issues wallet cards ( similar to credit card ) to ALL participatory workers . since2010 , OSHA is no more issuing any card to trainees outside USA . 

IOSH(Institution of Occupational Safety and Health)

 IOSH is institution of safety & health of UK , world's largest professional & research based membership body of safety professionals who research & give recommendations to statutory bodies of UK on matters pertaining to health & safety at workplace . 

Whereas the NEBOSH General Certificate is ten days in length the IOSH Managing Safely course is only four. The course is generally much easier to pass than the NEBOSH

Pyrophoric iron sulphides formation in Oil and Gas

Pyrophoric 
A pyrophoric material is a liquid or solid that, even in small quantities and without an external ignition source, can ignite within 5 minutes after coming in contact with air.


Pyrophoric iron sulphides form when iron is exposed to hydrogen sulphide, or any other compound that contains sulphur, in an oxygen deficient atmosphere. They are found frequently in vessels, storage tanks, and sour gas pipelines. Pyrophoric iron sulphides present a hazard when equipment and tanks are opened for cleaning, inspection, and maintenance. As the iron-sulphide compounds dry out and come in contact with air, they react with the oxygen and spontaneously ignite.

In oil and petrochemical industry, this only partially defines the concern.
We also need to be concerned with the fact the pyrophoric material can
create heat which can ignite residual hydrocarbons associated with the
equipment containing the pyrophoric material. 


  • Pyrophoric compound + oxygen (typically air) Oxide of the compound + heat
  • Sometimes with several intermediate reaction steps
  • Can be very reactive or very slow to react
  • Can vary with conditions, humidity, temperature, particle size, degree of
  • disbursement in air, etc. 


Pyrophoric form mostly on


  • Crude oil tanks
  • Asphalt tanks
  • Sour water tanks
  • Vessels in sour service such as coke drums, distillation columns, inlet
  • separators, pig receiver / launchers
  • Reactors
  • API Separators
  • Marine tankers and barges
  • Portable tanks and tote bins 


General Precautions to Avoid Pyrophoric Iron Fires

1.    The scraps and debris collected from cleaning of filters in naphtha / crude service must be kept wet and disposed of underground. 

2.    Tanks, reactors, columns, and exchangers in high-sulfur feed service must be kept properly blanketed with N2 during idle periods. 

3.    All equipment and structured packing must be properly water washed and kept wet when exposed to the atmosphere. 

4.    In processes where catalyst handling is required (such as in Hydrotreating and fluid catalytic cracking) caution must be taken during catalyst recharge or disposal. When unloading any spent coked catalyst, the possibility exists for iron sulfide fires. If the spent catalyst is warm and contacts oxygen, iron sulfide will ignite spontaneously and the ensuing reaction may generate enough heat to ignite carbon deposited on the catalyst. Therefore catalyst must be stripped of all hydrocarbons, cooled to about 50 o C and wetted with water to prevent it from igniting vapors. Once cooled, the used catalyst may be emptied into drums for later shipment to a regenerator or a disposal site. As the catalyst may be highly pyrophoric (containing iron sulfide, etc.), it should be dumped into drums containing an internal liner for shipment. The drum and liner should first be filled with inert gas, which is then displaced by the catalyst. The liner should be tied off and a small chunk of dry ice placed inside the drum before sealing. These precautions should protect against catalyst auto ignition.”

Incident:
In Shell refinery in the 1960s where the flare line had been opened for maintenance.  Several staff were standing directly downstream of the line and suddenly there was a huge ball of flame that shot out of the flare line and caused several extremely severe, disfiguring burns (including, ironically, the side of the body and face of the fire and safety department chief).  The cause of the flame was was determined to be pyrophoric iron, burning spontaneously on contact with air, which set off some hydrocarbon liquids still in the line.

Local Exhaust Ventilation [LEV] at workplace

The Control of Substances Hazardous to Health (COSHH) Regulations 2002 state that exposure to hazardous substances must be avoided completely, or adequately controlled where this is not practicable. The Regulations require control measures to follow a strict hierarchy and engineering solutions must be applied for the control of exposure before the use of personal protective equipment is considered.
Lines showing dust/gas particle flow

Effective LEV or dust/fume extraction can carry away airborne contaminants before they can be breathed in.

Local Exhaust Ventilation (LEV) systems can provide a very effective means of exposure control.

LEV systems capture airborne contaminants at the point of generation, preventing inhalation by workers in the vicinity. They vary in complexity, ranging from a simple single-point extract serving a single machine or process to complex multi-point installations serving several machines. However the basic elements are:

(i)  a hood or collector to capture the contaminant close to the point of generation

(ii)  ductwork to convey the contaminant away from the source

(iii)  a filter or air cleaning device to remove contaminant from the extracted airstream

(iv)  a fan or air moving device to provide the necessary air flow

(v)  ductwork to discharge cleaned air to the external atmosphere at a suitable point.

Know The Risks Of Asbestos at Work place

Some workplace hazards have an immediate effect, causing an injury or illness you can’t miss. Others, such as asbestos, take many years to do their damage. 
Asbestos is a naturally-occurring mineral used for fireproofing and many other applications. It is mined from rock in the form of a fiber that can be spun or woven into fabric and other products. Its many qualities led to widespread use before the serious health effects were common knowledge. Asbestos doesn't burn. It’s flexible, strong, resistant to chemical damage.

If you work in construction, maintenance or demolition. Off-the-job renovation of houses, antiques or vehicles can also put you at risk.
Asbestos usually is mixed with other materials. For example, some floor tiles contain a small amount of asbestos. The mineral can be found in sprayed fireproofing, sprayed insulation, fire doors, pipe and boiler wrap, building insulation in walls and ceilings, cementing compounds used in plumbing, older shingles and siding, brake linings and clutch pedals.

When asbestos or asbestos-containing products break apart, they release tiny fibers that can be breathed in. These fibers lodge in the lung where they set off serious illness.
Asbestosis is a chronic respiratory condition. The inhaled fibers irritate the lung tissues and cause scarring. Symptoms include shortness of breath and a crackling sound in the lungs when inhaling. The disease is disabling and usually fatal. Workers who have renovated or demolished buildings containing asbestos may be at risk.

Lung cancer is the cause of most deaths from asbestos exposure. Mining, milling, manufacturing and use of asbestos and asbestos products puts the worker at risk. Symptoms include a cough, change in breathing and shortness of breath. Smoking in combination with asbestos exposure increases risk of lung cancer.
Mesothelioma is a rare form of cancer, usually occurring in the thin membrane lining of the lungs, chest or abdomen. It is almost always linked to asbestos exposure. At risk are miners and textile workers.

Operations such as the following release asbestos fibers from asbestos-containing materials:
• drilling
• grinding
• buffing
• cutting
• sawing
• striking
To protect yourself from exposure, you need to know where asbestos is likely to be found in the facility. Head warning signs and markings. If in doubt, ask your supervisor or EHS professional before attempting to replace a fallen ceiling tile or crumbled insulation. If something is identified as asbestos in the facility and you see some damage to it, report it immediately.
