Hawthorne Experiment (Mayo Experiment)

The Hawthorne effect refers to the fact that people will modify their behavior simply because they are being observed. The effect gets its name form one of the most famous industrial history experiments that took place at western Electric's factory in the Hawthorne suburb of Chicago in the late 1920s and early 1930s.

However, subsequent analysis of the effect by the university of Chicago economists in 2009 revealed that the original results were likely overstated.

These experiments were originally designed to study the " Relation of quality and quantity of illumination to efficiency in industry". The surprising thing observed that the output has no relation with the level of illumination. The observer then realized that motivation of the individual has no relation with money or lighting intensity. They started to ask that what motivates an individual to work in groups. 

The psychologist named Elton Mayo was allowed to conduct series of experiments and important findings were;

  • Working in a small, harmonious group can have a significant effect on productivity.
  • Having a chance to air grievances seems to be beneficial to working relationship.
One of the essential principle observed was that when you show concern or pay attention to, there will be considerable betterment in performance. This is known as 'Hawthorne effect' or the 'somebody upstairs cares' syndrome.

KEY TAKEAWAYS

  • The Hawthorne Effect is when subjects of an experimental study attempt to change or improve their behavior simply because it is being evaluated or studies.
  • The term was coined during experiments that took place at Western Electric's Factory in the Hawthorne suburb of Chicago in the late 1920s and early 1930s.
  • The Hawthorne Effect is thought to be unavoidable in studies and experiments that use humans as subjects.

Accident / Incident Ratio Studies (F.E Bird Triangle)

The accident triangle, also known as Heinrich's triangle or Bird's triangle, is a theory of industrial accident prevention. It shows a relationship between serious accidents, minor accidents and near misses and proposes that if the number of minor accidents is reduced then there will be a corresponding fall in the number of serious accidents The triangle was first proposed by Herbert William Heinrich in 1931 and has since been updated and expanded upon by other writers, notable Franck E. Bird. It is often shown pictorially as a triangle or pyramid and has been described as a cornerstone of 20th century workplace health and safety philosophy. In recent times, it has come under criticism over the values allocated to each category of accident and for focusing only on the reduction in minor injuries. There is no shortage of data on incidents such as accidents or near misses. Some researchers have studied the figures in details and concluded that there appears to be a relationship b...

PERSONAL PROTECTIVE EQUIPMENTS (PPE's)

Personal Protective Equipment’s (PPE’s) Personal protective equipment’s (Safety helmet, shoes, coverall, goggles and ear plugs) are used when other control measure has been proved to be useful. It is considered as the last line of defense in the hierarchy of control. Eye and Face Protection – Safety Glasses Only approved safety glasses that meet regulatory (i.e., OSHA) and ANSI requirements shall be worn by site employees.   The frames shall be plastic and the lenses shall be impact resistant.   Side shields are required. Safety glasses shall be imprinted with Z87.1 to illustrate the glasses meet the regulatory and ANSI standard. Employees who wear prescription glasses shall wear safety glasses that incorporate their prescription into the lens or shall wear protection over their prescription glasses.   Over protection shall be plastic and impact resistant and shall display the Z87.1 stamp. For protection from bright sunlight or injurious light radiation, safet...

Indicators of Culture

 Indicators of Safety Culture within an organization include; Housekeeping. The presence of warning notices throughout the premises. The earing of PPE. Quality of risk assessments. Good or bad staff relationships Accident / ill-health statistics. Statements made by employees, e.g. "My manager does not care" ( negative culture) Some of these indicators will be easily noticed by a visitor and help to create an initial impression of the company. Safety Climate Assessment Tools The Health and Safety Laboratory (HSL) has published a safety climate tool that uses eight key factors mapped around 40 statements on which respondents are asked to express their attitude: Organizational commitment. Health and safety behaviors. Health and safety trust. Usability of procedures. Engagement in health and safety. Peer group attitude. Resources for health and safety. Accidents and near-miss reporting. The kit is available in a software format and will analyze and present the results as charts t...
