Take you quickly to understand how to assess and reduce mechanical risk

Mechanical injury, the term is not unfamiliar to every safety manager, it is the most common type of accident in our daily work. Our front-line machinery and equipment operation and maintenance personnel, if the attention is not concentrated, operation error or illegal operation can easily lead to such accidents, light limb mutilation, heavy loss of life.

So how to further do a good job in the prevention of mechanical injury accidents? In general, any improvement in the safety protection of machinery and equipment begins with a risk assessment. The full text is divided into risk analysis and risk management two links, the content is a little too much, today we mainly detail the risk analysis.

1. Determine the equipment to be evaluated

In this step, in addition to identifying the device being evaluated, you also need to confirm:

● Under what conditions the machine will be used;

● Who will use the machine and for how long;

● Machine life cycle (design, operation, maintenance);

Only when these conditions are established can hazard identification and risk assessment begin.

2. Risk identification

Risk is the cause of all dangerous situations. When exposed to dangerous factors, employees are in a dangerous state, and a safety accident may occur. Hazard identification is one of the most important steps in the risk management process. Therefore, a careful list of risk factors must be made, such as:

● The type of energy the device has, such as electrical energy, mechanical energy, thermal radiation and gravitational potential energy;

● Whether there is laser or invisible radiation electromagnetic;

● Whether there are noise, vibration and other physical hazards and harmful factors;

● Presence of dangerous substances or awkward operating positions (ergonomics)

These risk factors are then associated with the employee's operational activities.

3. Risk assessment

Badoun Technology provides professional safety assessment to help customers quickly discover mechanical safety risks of production equipment, the general process is:

01 Device life cycle assessment

Mainly includes: production, handling, installation, commissioning, scrap disposal.

02 Mechanical limitations of each link

# Restrictions on use: proper use and reasonable misuse that can be expected;

# Space limit: movement range, installation and repair space needed;

# Time limit: the expected life of the machine and its components;

# Other restrictions such as the use of materials, environment, cleaning.

03 Identify major hazards

# Mechanical hazards: such as extrusion, entanglement, cutting, winding, etc.;

# Electrical hazards: such as electric shock, burn, etc.

# Mechanical hazards: such as extrusion, entanglement, cutting, winding, etc.;

# Heat hazards: such as burns, frostbite, dehydration, etc.;

See below for more hazard illustrations:

04 Assess risk level factors

# Severity of risk (minor injury, serious injury or death)

# Probability of hazard occurrence (occasional or short, frequent or long);

# Avoid the possibility of danger (possible, impossible).

05 Proposed Measures

According to different actual conditions can be installed security protection devices, such as security fence, emergency stop, door locks, three controller and so on such devices.

Well, that's all for today, the second part of the risk control related issues, the next time we will continue to update!
