Safety Culture and Safety Performance


Let us discuss what makes some companies prone to accidents, while others are accident-free. Numerous studies have been conducted to determine the factors that make a company prone to accidents.

There is a growing body of empirical evidence concerning the impact of safety culture on safety performance. Numerous studies have investigated characteristics of companies with low accident rates, while generally comparing  them with similar companies with higher-than-average accident rates. A fairly consistent result of these studies conducted in industrialised as well as in developing countries, emphasises the importance of senior managers' safety commitment and leadership for safety performance (Chew 1988; Hunt and Habeck 1993; Shannon et al. 1992; Smith et al. 1978). 

Moreover, most studies show that in companies with lower accident rates, the personal involvement of top managers in occupational safety is at least as important as their decisions in the structuring of the safety management system (functions that would include the use of financial and professional resources and the creation of policies and programmes amongst others). 

According to Smith et al. (1978) the active involvement of senior managers acts as a motivator for all levels of management as it keeps up their interest through participation and for employees by demonstrating the management's commitment to their well-being. The results of many studies have suggested that one of the best ways of demonstrating and promoting humanistic values and people oriented philosophy is for senior management to participate in highly visible activities, such as workplace safety inspections and meetings with employees.

Many studies regarding the relationship between safety culture and safety performance pinpoint the safety behaviours of first-line supervisors by showing that supervisorsÊ involvement in a participative approach to safety management is generally associated with lower accident rates (Chew 1988; Mattila, Hyttinen and Rantanen 1994; Simard and Marchand 1994; Smith et al. 1978). 

This pattern of supervisors' behaviour is exemplified by frequent formal and informal interactions and communications with workers about work and safety, paying attention to monitoring workersÊ safety performance and giving positive feedback, as well as developing the involvement of workers in accident prevention activities. Moreover, the characteristics of effective safety supervision are
the same as those for generally efficient supervision of operations and production, thereby supporting the hypothesis that there is a close connection between efficient safety management and good general management.

There is evidence that a safety-oriented workforce is a positive factor for the firm's safety performance. However, the perception and conception of workers' safety behaviours should not be reduced to just carefulness and compliance with management safety rules, though numerous behavioural experiments have shown that a higher level of workers' conformity to safety practices reduces accident rates (Saari 1990). Workforce empowerment and active involvement are also documented as factors of successful occupational safety programmes. 

At the workplace level, some studies have offered evidence that effectively  functioning joint health and safety committees (consisting of members who are  well-trained in occupational safety, cooperate in the pursuit of their mandate and are supported by their constituencies) significantly contribute to the firmÊs safety performance (Chew 1988; Rees 1988; Tuohy and Simard 1992). Similarly, at the lower level, work groups that are encouraged by management to develop team safety and self regulation generally have a better safety performance than work groups subject to authoritarianism and social disintegration (Dwyer 1992; Lanier 1992).

It can be concluded from the previously mentioned scientific evidence that a particular type of safety culture is more conducive to safety performance. In brief, this safety culture combines:
(a) Top management's leadership and support;
(b) Lower management's commitment; and
(c) Employees' involvement in occupational safety. 

This form of safety culture is one that scores high on what can be conceptualised
as the two major dimensions of the safety culture concept, namely safety mission
and safety involvement.

Safety mission refers to the priority given to occupational safety in the firm's mission. Literature on organisational culture stress the importance of an explicit and shared definition of a mission that grows out of and supports the key values of the organisation (Denison 1990).

 Consequently, the safety mission dimension reflects the degree to which:

(a) Occupational safety and health are acknowledged by top management as a key value of the firm; and

(b) Upper-level managers use their leadership to promote the internalisation of this value in management systems and practices.

It can then be hypothesised that a strong sense of safety mission (+) impacts positively on safety performance because it motivates the individual members of the workplace to adopt goal-directed behaviours regarding safety at work and facilitates coordination by defining a common goal as well as an external criterion for orienting behaviour.

Meanwhile, safety involvement is when supervisors and employees join together to develop team safety at the low levels. 

According to Denison (1990), organisational culture supports the argument that high levels of involvement and participation contribute to better performance because:

(a) They create among organisational members a sense of ownership and responsibility leading to a greater voluntary commitment that facilitates  the coordination of behaviour; and

(b) They reduce the necessity of explicit bureaucratic control systems. 

Moreover, some studies show that involvement can be a manager's strategy for effective performance as well as a worker's strategy for a better work environment (Lawler 1986; Walton 1986).

Ergonomics in the Office-1

Millions of people go to work every day by sitting down in front of a computer. These jobs certainly don’t come with the same dangers as working in a factory or with heavy equipment but the office job can pose very real risks to health. Neck and back pain, shoulder stiffness and wrist pain are a few associated long-term hazards. Fortunately, learning a few things about proper ergonomics in the office can go a long way toward mitigating these risks. Here are a few tips to keep in mind:   Have a Well Designed Chair:  If sitting all day is unavoidable, then having a good chair to do it in is a must. Look for a chair that has firm cushioning and easy height adjustments. Lower back and well-placed arm support are mandatory. Good Posture:  This seems obvious, but the best chair will not do any good if the person sitting in it is slouched over all day. The spine should be straight, keeping the torso perpendicular to the floor. Arms should come straig...

Fire Hydrant System

A fire hydrant, (also known as fire pumps, hydrant boosters, fire water pumps)is a connection point by which firefighters can tap into a water supply. These are high pressure water pumps designed to increase the fire fighting capacity of a building by boosting the pressure in the hydrant service when mains is not enough, or when tank fed. A Fire Hydrant with fully-on valve , releasing pressure water. Safe Operating Procedure- Fire Hydrant The user attaches a hose to the fire hydrant, then opens a valve on the hydrant to provide a powerful flow of water.  Most fire hydrant valves are not designed to throttle the water flow; they are designed to be operated either full-on or full-off. Attaching Hose with Fire Hydrant When a firefighter is operating a hydrant, he or she typically wears appropriate personal protective equipment, such as gloves and a helmet with face shield worn. High-pressure water coursing through a potentially aging and corroding hydrant coul...

Hazards of Radio Frequency from Mobile Towers and Phones

Cell phone radiation damages DNA, inflicts cellular damage and creates a broad spectrum of health problems and diseases, including DNA mutation and cancer in humans. A group of scientist published this in a scientific journal “Oxidants and Anti oxidants in Medical Science” in March 2014, in a study called “Low intensity radiofrequency radiation: a new oxidant for living cells”. 76 studies (or 92.5%) proved that cell phone radiation inflicts cellular damage. Cell phone radiation affects production of Reactive Oxygen Species (ROS); these are molecules that form in our bodies as byproduct during normal metabolism of oxygen. A healthy human body has balanced, non health-threatening amounts of ROS. However, microwaves cause overproduction of ROS and dramatically increase oxidative stress – body’s inability to detoxify itself and repair the damage. Too much of ROS damages lipids, proteins and DNA in cells, and disrupts all kinds of natural cellular interacting signals, ...
