An occupational hazard is a hazard experienced in the workplace. Occupational hazards can encompass many types of hazards, including chemical hazards , biological hazards biohazards , psychosocial hazards , and physical hazards. Occupational hazard as a term signifies both long-term and short-term risks associated with the workplace environment and is a field of study within occupational safety and health and public health.

Occupational hazard

A physical hazard is an agent, factor or circumstance that can cause harm with contact. They can be classified as type of occupational hazard or environmental hazard.

Physical hazards include ergonomic hazards , radiation , heat and cold stress, vibration hazards, and noise hazards. Physical hazards are a common source of injuries in many industries. Employment of children may pose special problems. An engineering workshop specialising in the fabrication and welding of components has to follow the Personal Protective Equipment PPE at work regulations In a fabrication and welding workshop an employer would be required to provide face and eye protection, safety footwear, overalls and other necessary PPE.

Falls are a common cause of occupational injuries and fatalities, especially in construction, extraction, transportation, healthcare , and building cleaning and maintenance. According to published data from the Bureau of Labor Statistics , , private industry and government workers lost one or more days of work and around workers died as a result of fall injuries in the workplace.

Machines are commonplace in many industries, including manufacturing , mining , construction and agriculture , [9] and can be dangerous to workers. Many machines involve moving parts, sharp edges, hot surfaces and other hazards with the potential to crush, burn , cut , shear , stab or otherwise strike or wound workers if used unsafely. More than a quarter of these cases required more than 31 days spent away from work.

That same year, machines were the primary or secondary source of over work-related fatalities. Power tools , used in many industries, present a number of hazards due to sharp moving parts, vibrations, or noise. The transportation sector bears many risks for the health of commercial drivers, too, for example from vibration, long periods of sitting, work stress and exhaustion.

These problems occur in Europe but in other parts of the world the situation is even worse. More drivers die in accidents due to security defects in vehicles. Long waiting times at borders cause that drivers are away from home and family much longer and even increase the risk of HIV infections. Confined spaces also present a work hazard. The National Institute for Occupational Safety and Health NIOSH defines "confined space" as having limited openings for entry and exit and unfavorable natural ventilation, and which is not intended for continuous employee occupancy.

Spaces of this kind can include storage tanks, ship compartments, sewers, and pipelines. In , around U. Since noise-induced hearing loss, while entirely preventable, is permanent and irreversible, it is vital that companies and their employees are aware of limits and prevention methods available. Both organizations work to set and enforce standards for occupational noise exposure and ultimately prevent hearing loss. Temperature extremes can cause a danger to workers. Overexposure to freezing conditions or extreme cold can result in a risk to many workers.

Employees who work outdoors in the winter months such as fishers, hunters, divers, hydro and telecommunications linemen, construction workers, transportation workers, military personnel, emergency response workers, and those work in the refrigerated warehouse are especially vulnerable to cold.

Use of personal protective equipment such as insulating clothes, gloves, boots, and masks, radiant heaters as a part of engineering controls and safe work practices are used to minimize the risk of cold injuries.

Workers who are working in laundries, bakeries, restaurant kitchens, steel foundries, glass factories, brick-firing and ceramic plants, electrical utilities, smelters , and outdoor workers such as construction workers, firefighters, farmers, and mining workers are more vulnerable to exposure to extreme heat. Engineering controls such as air conditioning and ventilation, training to build up a level of tolerance to work in extreme heat conditions and use of cooled protective clothing can help to reduce heat-related illnesses.

Electricity poses a danger to many workers. Electrical injuries can be divided into four types: fatal electrocution, electric shock , burns, and falls caused by contact with electric energy. It can be fatal and can result in serious and permanent burn injuries to the skin, internal tissues and damage to the heart depending on the length and severity of the shock. Electric shocks can result in the injuries like muscle spasms , palpitations , nausea , vomiting , collapse, and unconsciousness.

According to the Bureau of Labor Statistics , a total 1, accidents occurred due to contact with electric current between and and out of that , the highest number of electrical fatalities occurred in the construction industry.

Electrical injuries are preventable through safe work practices like keeping electrical tools properly maintained, de-energizing electrical appliances before inspection or repair, and exercising caution when working near energized lines. Sunlight is the most commonly known physical hazard which affects the people who work outside. Some commonly used medicines such as nonsteroidal anti-inflammatory drugs NSAIDS , antihistamines , tetracycline , thiazides , sulfa antibiotics , and diuretics increase sensitivity to sunlight and resulting in skin rashes and sunburn.

UV rays directly from sunlight and indirect sun exposure, such as light reflected by snow and light-shaded sand can penetrate worker's uncovered skin. Personal protective equipment , engineering , and administrative controls such as the provision of shade cover, and rotating job shifts can minimize the risk of sun exposure for outdoor workers.

Vibration has long been recognized as a serious occupational hazard. Continuously repeated exposure to high levels of vibration results in injuries or illnesses. Vibration exposure is classified into two general types: hand-arm and whole-body vibration. It is a known causative factor for other ergonomic-related fatalities.

A Combination of control measures such as redesigning the appliances to reduce vibration exposure, using machines that are designed to decrease the vibration transmitted to the operator, implementing speed limits, scheduling regular work breaks, posture changes or job rotation to reduce exposure time, providing training, information and supervision on adjusting and operating equipment can be used for successful vibration exposure reduction. Lighting , and air pressure high or low can also cause work-related illness and injury.

Asphyxiation is another potential work hazard in certain situations. Musculoskeletal disorders are avoided by the employment of good ergonomic design and the reduction of repeated strenuous movements or lifts.

Ionizing alpha, beta, gamma, X, neutron , and non-ionizing radiation microwave , intense IR, RF, UV , laser at visible and non-visible wavelengths , can also be a potent hazard.
