Types of Risk Assessment in Safety

According to OSHA four basic types of risk assessment should be carried out in workplace

1- Baseline risk assessment 
2- Generic risk assessment
3- Continuous risk assessment
4- Specialized risk assessment 


1- Baseline risk assessment
This is the initial assessment of risk in a workplace. It is a broad assessment and includes all activities taking place on site. A baseline HIRA (Hazard Identfication and Risk Analysis) is done to establish a risk profile and is used to prioritise action programmes for issue-based risk assessments.

2- Generic risk assessment
This risk assessment is used where the same type of task is carried out at different workplaces in the same way (e.g. risk assessments of a number of warehouses storing similar goods). To do a generic risk assessment, perform a baseline risk assessment and then use this for similar work activities that involve comparable risks.

3- Continuous risk assessment
The continuous risk assessment is an informal risk assessment performed on an on-going basis in the workplace. It's usually performed by a supervisor who'll observe employees performing their tasks as part of his daily responsibility. From this observation the risk related to the specific performance of the task is assessed and the supervisor will stop the employee from continuing the task should it present too high a risk.

4- Specialized risk assessment 
In the field of HIRA there are several methods available for determining specific risks associated to each individual workplace. These models each have a specific application and are used to achieve specific objectives. 

Once you’ve decided on which risk assessment to perform, you’ll need to decide which model you’ll employ. In the field of hazard identification and risk assessment there are several methods available for determining risk in the workplace. These models each have a specific application and you’ll use them to achieve specific objectives.


Note:

As for Risk Analysis their are only two types which are;

1. Qualitative Risk  prioritizes the identified project risks using a pre-defined rating scale. Risks will be scored based on their probability or likelihood of occurring and the impact on project objectives should they occur.

2. Quantitative Risk assigns a projected value(usually this value is stated in terms of cost or time) to the risks that have already being ranked by the previous process 'perform qualitative risk analysis'.

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 ma

Nuclear Biological and Chemical Terrorism-1

Introduction Terrorism is a criminal act that influences an audience beyond the immediate victim. The strategy of terrorists is to commit acts of violence that draws the attention of the local populace, the government and the world to their cause. The terrorists plan their attack to obtain the greatest publicity, choosing targets that symbolise what they oppose. The effectiveness of the terrorist act lies not in the act itself, but in the public's or government's reaction to the act. Terrorism has become a global threat and needs to be controlled from the root level to the international level. Governments throughout the world are realising that terrorism is a serious threat. The bombing of the World Trade Centre in 2001 was one of the deadliest terrorist episodes in the world. There are various types of terrorism  nuclear, biological and chemical (NBC) terrorism. Different types of terrorism have been defined by lawmakers, security professionals and scholars. Types

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,
