What is Workplace Safety?

Workplace safety, also referred to as labor safety or occupational safety, is a top priority in every workplace. It refers to the implementation of policies, procedures, and measures designed to ensure the health and safety of employees in the workplace. Risk assessment determines the dangers and hazards in each workplace environment. But how has the modern workplace become safer? How is workplace safety being ensured in various evolving industry landscapes?

The answer: Automation and digitalization in companies. The Internet of Things (IoT) and robotics play an important role here. In order to digitalize occupational safety, tools and methods like wearables, environmental sensors, and location tracking and geo-fencing are commonly used. The following sections explain how automation and digitalization contribute to work health and safety (wh&s) in different industries.

Workplace Safety in Industrial Environments

In Industry 4.0 and manufacturing, IoT sensors embedded in machinery enable continous condition monitoring and predictive maintenance (PdM Maintenance). Predictive maintenance systems use the data captured by these sensors to predict when a machine is likely to fail. This enables proactive maintenance to prevent unexpected breakdowns and machine failures that could result in accidents. Additionally, collaborative robots (cobots) are designed to work alongside human workers. Cobots can take over dangerous tasks such as heavy lifting, welding, and also operate in hazardous environments.

Smart personal protective equipment (PPE) like helmets, ear plugs, protective eyewear, and clothing have integrated electronic components such as sensors, RF modules, and data carriers to enhance the protection of workers. This allows for applications in geo-fencing and geo-positioning, for example. Workers equipped with smart PPEs can be monitored to ensure that they stay in safe zones. By monitoring and measuring the body temperature of workers, smart wearables can also send alerts to remind workers to hydrate themselves in high-temperature environments. Studies suggest that smart glasses with augmented reality (AR) also contribute to workplace safety and health.

As a result of the COVID-19 pandemic, there have safety measures were heightened in many workplaces. Insight Sip, a French manufacturer and designer of ultra-miniaturized electronic components developed the solution “Security Bubble Covid-19” to ensure compliance with social distancing. This solution makes use of Near-Field Communication (NFC), BLE and Ultra-Wide-Band (UWB) technologies. PPEs are equipped with tags that are programmed to trigger alarms in case they get too close with other tags. This smart PPE solution can be used in a variety of different workplaces, and is an example of digitalization in occupational safety. Workplaces like factories, warehouses, construction sites, offices, restaurants, supermarkets, shops, schools, universities, and museums can benefit from this solution.

NFC technology and Radio Frequency Identification (RFID) are often used as solutions for access control to ensure that only authorized employees can enter dangerous areas.

Workplace Safety in the Construction Industry

IoT technologies like GPS and LoRaWAN trackers and sensors are used for geo-fencing and tracking on construction sites. These trackers with positioning technologies prevent vehicle collisions and are also used to ensure that employees stay in safe zones.

As explained in the section above, smart PPEs can also be used in construction sites. These include smart helmets, boots, and glasses, for example.

Drones equipped with cameras are used for inspection purposes. These drones are used for inspection in dangerous or hard-to-reach locations, such as roads, skyscrapers, bridges.

Less common are robotic exoskeletons such as power gloves, back support, arm and shoulder supports, and whole-body suits that are designed to help workers lift heavy loads in construction sites.

Workplace Safety in Healthcare

As part of digitalization in healthcare, staff duress solutions based on Bluetooth Low Energy (BLE) and Real Time Locating Systems (RTLS) improve the safety of healthcare workers in emergency situations. Smart PPEs can be used to ensure that social distancing regulations are complied with in hospitals and healthcare facilities. Service robots are used to support healthcare workers in lifting patients. This eliminates the risk of injury for both the patients, and the worker.

Workplace Safety in Logistics

Automation plays a big role in increasing worker safety in logistics and transportation. This is part of digitalization in logistics. In modern high-speed and high-pressure logistics environments, orders must be processed, prepared, and shipped as quickly as possible. Forklifts and workers race throughout warehouses and facilities at risk of physical strain and collisions. The use of autonomous mobile robots (AMRs) is a solution that automates the warehouse. AMRs can handle transport tasks and heavy lifting that may cause human injuries. Indoor navigation systems based on RTLS, RFID, and BLE, for example, can be used to prevent forklift collisions.

Workplace Safety in Public Spaces

IoT technologies also contribute to ensuring workplace safety in public spaces like offices, school, and universities.

Environmental sensors can be placed throughout buildings and facilities to monitor parameters such as water, temperature, and air quality. IoT-based indoor monitoring systems notify employees when hazardous substances are detected.

Connected surveillance cameras and smart locks enhance physical security in office buildings. Occupancy sensors and smart ID systems based on RFID or NFC ensure that only authorized personnel can access certain areas. This prevents unauthorized entry and potential security breaches.

In universities and schools, occupational safety systems like advanced surveillance systems, smart access control, and emergency notification systems work in tandem to ensure the safety of both students and staff. In case of emergencies, IoT-enabled notification systems can quickly disseminate alerts and instructions across the campus via connected devices, ensuring timely and coordinated responses.

Laws and Regulations for Occupational Safety

Occupational safety is part of labor rights, and is governed by a range of occupational safety laws and regulations designed to protect workers from hazards and ensure a safe working environment. By law, employers need to provide workplace-related training and instruction on a regular basis. This often happens annually. This is part of Section 12 of the Occupational Safety and Health Act, for example. In Germany, each state has its own occupational health and safety supervisory authority that is responsible for a specific area. Some of the key laws and regulations issued by workplace safety authorities or are listed below.

Examples from the United States are the Occupational Safety and Health Act (OSH Act) of 1970, and the Federal Mine Safety and Health Act (MSH Act) of 1977. The goal of the OSH Act is to ensure safe and healthy working conditions for men and women. It sets out specific standards for various industries, including construction, maritime, and industry, for example. The MSH Act regulates safety and health in the mining industry to prevent disasters, hazardous conditions, and promote safe working practices.

In the European Union (EU), examples include the Framework Directive 89/391/EEC and the REACH Regulation (EC) No 1907/2006. The Directive 89/391/EEC involves the introduction of measures that encourage the improvement of worker health and safety. The European Agency for Safety and Health at Work describes this as a “Framework Directive” for occupational safety and health (OSH). The regulation (EC) No 1907/2006 concerns the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH). This regulation was put into place to ensure that workers and the environment are protected from hazardous substances. Other examples include the Act on the Protection of Young People at Work, the Ordinance on the Protection of Children at Work, the Ordinance on Preventive Occupational Health Care, and the Ordinance on the Use of Personal Protective Equipment.

The Supply Chain Diligence Obligations Act, known in German as the “Lieferkettensorgfaltspflichtengesetz (LkSG)”, is a German law with the goal of protecting and promoting human rights and environmental standards along global supply chains. It is also known as the Supply Chain Act, and includes protection against child labor, the protection of the environment, and the right to fair wages.

Under the Product Safety Act (Produktsicherheitsgesetz), the product design must meet various safety requirements to be eligible for sale in Germany. This applies to products used by consumers, as well as to products used by employees in the workplace. This law promotes the health protection of workers.

“We rolled out the solution to 7,000 staff members. We activated their badges and did some surveys to assess safety. What we found is that approximately 84 percent of staff feel that they are somewhat safe at work. Through this intervention, there was an increased awareness around areas or situations where they are not safe. Associated with that, there is the ability to generate immediate real-time support to diffuse the situation and to increase the incident reports that accompany this. We had 167 panic activations over our study period and we continue to collect that data set. We reduced our false alarm rate from 32 percent to 11 percent.”
