LOTO locks are designed to be challenging to pick, with a plastic body and a hard core. The plastic body is vulnerable to damage for easy removal, but it is also cheap to produce, lightweight, and the red colour won't wear off. LOTO locks are used in safety systems, where two devices are shut down and locked out.

What You'll Learn
LOTO locks are cheaper to produce
LOTO locks are designed to be challenging to pick, with some of the most pick-resistant locks produced by Master Lock. These locks are designed to be destroyed if the key is lost or misplaced, rather than picked, bypassed, or master keyed. This is an important safety feature for locks that are used to secure dangerous machinery.
LOTO locks are often made with plastic bodies, which are cheaper to produce than other materials. The plastic body suits the requirements of a LOTO lock as it does not need to protect the lock from being forced open. The use of plastic also keeps the weight of the lock down and ensures that the red colour won't wear off.
In addition to the cost savings associated with plastic-bodied locks, the key variation is another important factor in the use of LOTO locks. The unique keys reduce the likelihood of someone removing the wrong LOTO lock from a system, which could have dangerous consequences.
While the plastic bodies of LOTO locks are vulnerable to damage, this is a trade-off that is accepted for the cost savings and other benefits that the material provides. The vulnerability of the plastic body also ensures that the lock is not pick-resistant, in line with OSHA guidelines. Overall, the use of plastic in LOTO locks is a cost-effective solution that helps to improve safety and reduce the likelihood of accidents.

The red colour of LOTO locks won't wear off
Lockout-Tagout (LOTO) is a critical safety procedure that protects workers from hazardous energy sources when maintaining or servicing equipment. LOTO locks are colour-coded to help identify who has locked out equipment and for what purpose, thereby reducing the risk of confusion and improving workplace safety.
Red locks are the most recognised LOTO locks and are typically assigned to individual workers. When a technician applies a red lock, only they can remove it, ensuring their safety while working on a machine. For instance, a machine operator may isolate a conveyor belt for maintenance and apply a red lock to prevent unexpected reactivation.
The colour red is particularly suitable for LOTO locks as it is a distinct, highly visible colour that can easily catch the attention of workers. The red colour of LOTO locks is also advantageous because it is less likely to wear off over time, thanks to the durable plastic material used in the lock's construction. This ensures that the locks remain clearly identifiable and effective in their role of enhancing workplace safety.
In addition to their colour, LOTO locks are also made of plastic to perfectly suit the requirements of a LOTO. Plastic locks are cheaper to produce, lighter in weight, and do not require protection from forced entry. The plastic body is intentionally designed to be vulnerable to damage for easy removal in emergency situations. This frangible quality of the plastic body is particularly useful when a device becomes unsafe while the LOTO is installed, allowing for quick removal using bolt cutters or a blow torch.
To summarise, the red colour of LOTO locks is important for worker safety and will not wear off due to the durable plastic construction. The colour red immediately identifies the lock as a standard LOTO lock, assigned to an individual worker, and helps ensure a safe working environment.

LOTO locks are lighter
LOTO locks are often made of plastic, with the bodies being particularly vulnerable to damage for easy removal. The plastic body suits the requirements of a LOTO, as it is cheaper to produce and lighter than other materials. The colour is also long-lasting, with the red colour of the plastic not wearing off.
The plastic LOTO locks are also designed to be pick-resistant. Master Lock, for example, has made their plastic LOTO locks some of the most pick-resistant of their entire line of products. This is in line with OSHA guidelines, which state that if a key is lost, the lock is to be destroyed, not picked.
The vulnerability of the plastic body to damage is intentional, as it is easier to remove than other materials. This is particularly important in emergencies, where equipment may need to be cleared quickly. In addition, the use of plastic LOTO locks can help reduce costs, as they are cheaper to produce than locks made from other materials.
The light weight of plastic LOTO locks is particularly advantageous in certain applications, such as in large shipyards, where the reduced weight can make it easier for workers to handle and manoeuvre the locks. The light weight of the locks can also help improve safety, as it reduces the risk of injury when handling or transporting the locks.

LOTO locks are challenging to pick
LOTO locks are often made of plastic due to their low cost, light weight, and ease of identification. The red colour of the plastic is highly visible and won't wear off, making it easy to identify which devices are locked out and require authorisation for operation. The plastic body also makes the locks cheaper to produce and lighter to transport and use.
While the plastic body of LOTO locks offers some advantages, it also has its drawbacks. Plastic is more vulnerable to damage than other materials, which can make it easier to remove the lock without picking it. However, this is balanced by the fact that the locks are designed to be challenging to pick.
LOTO locks are specifically designed to be pick-resistant. This is because, in the event of a lost or misplaced key, the recommended procedure is to destroy the lock rather than attempt to pick, bypass, or master key it. This helps to prevent unauthorised access and potential accidents or mishandling of equipment.
The challenge of picking a LOTO lock is attributed to its unique pinning mechanism. Unlike traditional locks, LOTO locks typically feature all spools except for one lightly serrated driver pin, and the key pins are not serrated. This design makes it more difficult for a standard lock pick to engage and manipulate the pins effectively.
Additionally, the plastic body of the lock serves as a further deterrent to picking. While the plastic body can be forced open, it is not as easily manipulated as a traditional metal lock body. The plastic construction may also make it more difficult to use traditional lock-picking tools and techniques, requiring specialised knowledge and skills to successfully pick the lock.

LOTO locks are easily identifiable
LOTO stands for Lockout-Tagout, and these locks are designed to prevent the accidental or unauthorised operation of equipment or machinery. They are often used in conjunction with a tag-out procedure, where a tag is attached to the locked equipment, providing additional information or instructions. This two-step process helps to improve safety and reduce the risk of accidents.
The distinct appearance of LOTO locks, with their red colour and plastic bodies, makes them easily recognisable, even from a distance. This quick visual identification is crucial in emergency situations, where every second counts. Additionally, the bright colour of LOTO locks can serve as a visual reminder to follow proper safety procedures, helping to create a culture of safety awareness in the workplace.
While the plastic bodies of LOTO locks may seem vulnerable, they serve an important purpose. The plastic material is chosen because it is cheaper to produce, making LOTO locks a cost-effective solution for businesses, especially those with a large number of locks in use. Additionally, the plastic body makes the locks lighter, which can be advantageous in certain applications.
Furthermore, LOTO locks are designed to be challenging to pick, with some manufacturers creating locks that are extremely pick-resistant. This feature ensures that the locks cannot be easily bypassed, enhancing their security and reliability. Overall, the distinct features of LOTO locks, including their colour, material, and pick-resistance, make them easily identifiable and well-suited for their important safety functions.
