Workplace Exposure Limits (WEL)

An Workplace Exposure Limit is an upperlimit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect Workplace safety and health.

Types of Exposure Limit:

Short term exposure limit (STEL)- maximum concentration of airborne contaminates too which employees may be exposed for a short period of time equal to 15 minutes.

Long term exposure limit (LTEL)- maximum concentration of airborne contaminants to which employees may be exposed over their entire working life for a reference period equal to 8 hours per day, 40 hours per week.

Purpose of WELs

The purpose of WEL is to combat the ill-health effects of being exposed to very high levels of the substance for quite short periods of time (sudden acute effects), and also to combat the ill-health effects of being exposed to relatively low concentration of substance for prolonged period or all hours of working day through an entire working life time (delayed chronic effects).

The aim is to ensure that the exposure to contaminants is below WEL, by having arrangements for monitoring the concentration of airborne substance in workplace along with suitable controls such as extraction system.

Limitations of WELs

Workplace exposure limits are set based on inhalation, whereas other routes are not considered. They are set with reference to male physiology of certain European countries and USA, hence it will have significant impact on race and gender. 

They becomes invalid if the environmental parameters, such that humidity temperature etc. in which the tests are carried out, vary largely with actual workplace environment. They don’t account for synergistic effect of multiple substances. 

Some limits are only ‘guidelines’. Some limits do not consider all the possible health effects of a substance such as dermatitis would not be considered with an airborne limit.

TYPES OF FIRE EXTINGUISHERS

PORTABLE FIRE EXTINGUISHERS

Portable fire extinguishers are also known as chemical fire extinguishers or First Aid Fire Fighting Appliances.

These extinguishers are highly useful to prevent a small fire from becoming a big one, provided these are used when the fire is just in its starting stage, say within first five minutes. These are light weight, small in size which can be easily carried by hand.

Larger models of certain types are also available which are known as "engines". These are mounted on trolleys, which can be moved manually or toed to motor vehicles.

• Water Type Extinguishers
• Foam Extinguishers
• Dry Chemical Powder Extinguishers
• Halon Extinguishers
• Carbon dioxide Extinguishers

Scaffolding

Scaffolding may be erected using traditional tubes and working platform.

The following terms are used to identify the component parts of a traditional tube and fitting scaffold:

• Standard: upright member.
• Ledger: horizontal member normally in the direction of the larger dimension of the working scaffold.
• Transom: horizontal member normally in the direction of the smaller dimensions of the working scaffold
• Putlog: horizontal member, flattened on one end, spanning from a ledger to sit in the pointing of brickwork.
• Raker: an inclined load-­bearing member used to support a cantilevered working platform.
• Façade bracing: bracing parallel to the façade of the building
• Ledger Bracing: Bracing perpendicular to the face of the building.
• Eyebolt: means of securing scaffold to the building.
• Through Tie: means of securing scaffold to the building.
• Reveal Tie: means of securing scaffold to the building.
• Base plate: plate used for spreading the load in a standard over a greater area; a base jack is a base plate with a means of vertical adjustment.
• Sole Board: a timber plank positioned beneath two or more base plates to distribute the scaffold load more evenly over the ground.
• Coupler: device used to connect two tubes.
• Platform: one or more platform units in one level within a bay.
• Bay: the distance between pairs of standards.
• Lift: a storey.

Biological Hazard - Biological Agents

Biological agents are micro – organisms such as:

Fungi

Moulds, yeast and mushrooms mostly harmless to human but some can cause disease such as athlete’s foot and farmer’s lung, both fungal infections.

Bacteria

Single celled organisms that are found in vast numbers in and on the human body. Some are beneficial while others can cause disease such as legionnaires, leptospirosis etc.,

Viruses

Very small infections organisms that reproduction on living cells of human body. Example – Hepatitis

Possible routes of Entry for a Biological Agent

The possible routes of entry for a biological agent into the body would be 

inhalation – airborne micro-organisms, 

absorption through the skin, injection for example through cut and grazes, exchange of body fluids, and 

ingestion – contaminated food.

Control Measures to Reduce Risk of Exposure to Biological Agent

• In order to reduce the risk of infection from biological organisms we can adopt a number of control Measures such as cleaning and disinfecting
• The use of personal protective equipment like respiratory protection, aprons and gloves
• Engineering controls such as containment for example in glove boxes, can also be provided with local exhaust ventilation and the use of microbiological safety cabinets
• The introduction of procedures for the disposal of waste
• The prohibition of eating or drinking in the work area
• Vermin control
• Procedures for site monitoring and health surveillance
• Immunization and a good standard of personal hygiene.

Routes of Entry of Hazardous Substances

Inhalation:
This is the most important route of entry as it allows the substance to directly attack lung tissue and, in some cases, to enter the blood stream and attack other organs of the body. The lungs are an active pump, drawing in air from the environment and the majority of occupational ill-­health produced by agents is caused by inhalation. Gases, such as carbon monoxide, enter the body by inhalation.

Ingestion:
occurs through the mouth. This can be accidental - such as by drinking from an unlabelled container or by poor hygiene -  eating, drinking or smoking in a contaminated environment. Respiratory defence mechanisms also push inhaled particles, such as dusts, into the throat and mouth, most of which will then be swallowed;

Absorption:
Occurs through the skin and across membranes, e.g. ammonia into the eye. Many solvents will penetrate unbroken skin and can enter the blood stream. Other substances can enter via cuts or abrasions;

Direct Entry:
Occurs through open wounds on the skin, such as dermatitis, tetanus infection and leptospirosis (Weil’s disease) from female rat urine;

Injection (skin puncture):
Caused by contact with liquids or gases under pressure or accidental puncture of the skin with contaminated sharp objects, e.g. HIV.

Fire Risk Assessment

The Fire Risk Assessment is a important method for avoiding fire in the working environment. 

It enables employers to identify and protect staff against any known flame dangers, by creating powerful techniques - for example plotting how to store and utilize such materials securely.

A number of steps must be followed to conduct a Fire Risk Assessment: 

Step 1: Recognize the fire hazards, distinguish sources of ignition, fuel and oxygen.

Step 2: Identify the people at danger. This includes any individual who is in or around the premises, for example, employees, contractors, visitors,customers, and others.

Care must be taken to distinguish individuals who are at specific danger - for children, youngsters, the elderly or anybody with an inability.

Step 3: Evaluate, evacuate or decrease and secure those at danger. Assess the danger of a fire and the risk to people from fire.

Evacuate or decrease hazards and the danger. Protect by giving fire precautions,

equipment and by procedures.

Step 4: Record, arrange, advise and prepare. 

Record the significant findings and the activity that has been taken. Talk about and offer the findings with others. Develop an emergency arrangement in the case of a flame. Inform relevant people and provide training.

Step 5: Review the fire risk assessment regularly.

Review your fire risk assessment plan regularly to ensure it remains relevant and up-to-date. Update and change your arrangement if required.
