Industrial Safety Systems

What is Industrial Safety? Types of Industrial Safety Systems

Industrial safety is universally considered a necessity because it creates a positive, motivating environment.

To protect workers in hazardous areas, industrial safety systems were developed. Industrial safety systems protect people and protect the environment from chemical reactions.

Although they do not control processes, these systems are useful when the process cannot be controlled with ordinary methods. They are mounted as a safety measure and are quickly becoming a necessity in every workplace.

Safety regulations are becoming more stringent. There is also a need to increase production capacity and produce faster. This makes it more difficult for workers to operate machinery at higher risk and faster speeds. Equipment operators and manufacturers place a lot of emphasis on engineering and the application international standards when it comes to safety.

The effectiveness of a safety program is not solely dependent on technical and regulatory aspects. It must also be based on a detailed functional analysis of the organization, production processes and the human factor. Machinery safety was in the past viewed as a cost.

What is Industrial Safety System?

Safety technologies can be considered an investment in productivity and business efficiency. Safety switches and relays are now very common. Safety mechanisms and PLCs have also been popularized by the use of integrated technologies. However, they have had a limited impact upon planning and system engineering.

The instrumentation component and program landscape includes solutions that can control all aspects of the possible risks in the machinery and systems used in production and transformation.

Sensors, such as smoke and fire detectors, allow for automatic intervention to eliminate the causes and effects of combustion and fire. Meanwhile, detectors for gases or other airborne compounds protect the area around the equipment. Safety PLCs can prevent unsafe movements and stop unauthorized personnel from entering hazardous areas. In order to lower risk levels, it is important that accurate and reliable instruments and devices are used.

What are the various types of Industrial Safety Systems available?

There are many types of safety systems available. Their use will depend on what industry they are in. Here are some examples.

  • Functional Safety System
  • Electrical Safety System
  • Process Control Systems
  • Safety Shutdown Systems
  • Shut down in an emergency
  • Fire and Gas Systems
  • Intrinsic safety system

1. Functional Safety System

Functional safety is the first concept of safety. Functional safety is the safest type of safety. It involves the system’s ability to function properly in response to an initial electrical signal, electronic and programmable parameters. ISO 13849 (Safety machinery – Safety-related components of control systems) is the main standard that governs functional safety. IEC 62061 (Safety machinery – Functional safety of safety related electrical, electronic, and programmable control systems), IEC 6150 (Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems), and IEC 61511 (Functional safety – Safety instrumented systems for the process industry sector). Important to remember that ISO 13849-1 stipulates that in order to evaluate the safety-control system’s performance, the probability of calculate dangerous failures per hour (PFHd), it is necessary to take into account the following: This indicator is based on the random failure rates of all components in a system.

It is especially important for PLCs because it describes safety functions and general requirements to design and protect control systems. In order to design automated systems that are completely safe for personnel and production are known as Safety Integrity Level (SIL). IEC 62061 and Good Automated Manufacturing Practice (GAMP). Notable is also the standard ANSI/ISA-99 which was developed in accordance with international standards and defines safety levels. On a scale of 0-4, the equipment used in production and operations.

2. Electrical Safety System

Electrical safety is the second type of safety in industry. By designing and building electrical equipment, you can achieve electrical safety. Avoid direct contact with any electrical cables or other electrically-conductive parts. Avoiding hazards from electrical cables and other electrically conductive parts is another important goal for manufacturers. Indirect contact with ground or another conductor when it happens to be in tension. EN 60204 and EN 60205 are the main standards in electrical safety. (Safety machinery – Electrical equipment of machine), EN 60947-5 Low-voltage controlgear and switchgear, and NFPA 79 (Electrical Standard for Industrial Machinery) for the US market. The Machinery Directive, which is the current standard, defines the risk assessment, elimination or reduction as follows: Principle of safety integration in the design and construction machinery. Refer to ISO 12100 (Safety and machinery – General principles of design — Risk).

3. Process Control Systems

These devices are used to monitor the production environment and regulate the production process electronically. A laser diode can be used to detect gas or liquid present in the environment. The processor will identify the signal received if the liquid or gas is identified by transforming their frequency signature into a digital signal.

4. Safety Shutdown Systems

These systems can be especially useful in a state of emergency because they will automatically shut down any system that is deemed unsafe. They can be connected to the gas and fir systems in order to create a safe working environment.

5. Emergency Shutdown System

The emergency shutdown refers to a shutdown that is triggered by a failure of a production utility or significant plant parts. The impact of emergency situations is minimized by an emergency shutdown (ESD).

ESD systems are designed to protect employees and machinery, as well as preventing any environmental impact from process activities. ESD is considered to be one of the most important safety mechanisms that a plant can provide.

6. Fire and Gas Systems

These systems are highly sensitive and intelligent. They sense the danger at an early stage. They also sense the danger and provide visual and audible signals to warn others. These devices can be activated manually or automatically.

7. Intrinsic safety system

Intrinsic safety based on the ATEX Directives 2014/34/EU & 1999/92/EC is also to be considered. The technical principle that prevents the danger of explosion or fire from electrical devices and electronic instrumentation is called intrinsic safety. This safety is provided at the level of power circuitry by galvanic isolation or Zener barriers. Photoelectric barriers (i.e. These devices are electro-sensitive and can be used to ensure high levels in machinery productivity and machine efficiency.

What is the importance of an industrial safety system?

A industrial safety management system that is effective provides the tools to engage people and keep them aware of the hazards they face every day. This includes doing the same job over and over again as they have done for years. Software for safety compliance allows you to track and complete pre-shift operational inspections. This ensures that critical setup tasks are completed and documented.

Industrial safety software can keep all operations up-to date in real-time, making them accessible to any operator at any time. Even something as simple as updating the pre-shift safety inspection with important new information can save a life or limb.

Final Words

All types of fire protection require that electrical devices installed in areas at high risk of explosion be classified into T1 through T6 temperature classes. Specific fire-protection methods must be used by the device manufacturer to ensure that each device is safe. IEC 60079-11 is a key standard in this area. The regulatory framework is complex and highly specialized, which is continually evolving, reflects the sensitive nature of safety issues.
