A safety padlock is a personal safety lock belonging to a single worker, used in lockout–tagout (LOTO) procedures to keep an energy source shut off for the duration of maintenance. In the field it is also known as a LOTO lock or LOTO padlock. The worker fits their padlock onto a circuit breaker lockout device, valve lockout or lockout hasp; as long as the key stays in their pocket, no one else can re-energize that point.
They should not be confused with ordinary padlocks sold for property protection. LOTO locks have a lightweight, impact-resistant body, are suitable for colour coding and carry a warning marking. The most important difference is the key-retaining feature: the key cannot be removed from the cylinder until the lock is closed, reducing the risk of a lock left open or a lost key.
At Sofilx LOTO, we offer these locks in 38 mm and 76 mm shackle heights, in red, yellow, blue, green, black, white, orange and purple. You can create a colour and key scheme by person, team or department.
Product guide
Types of Safety Padlocks
38 mm steel shackle padlocks
The most commonly preferred type for panel, circuit breaker and valve lockout; its short, compact shackle fits easily into lockout hasp holes.
38 mm plastic shackle padlocks
Its non-conductive shackle stands out at points with electrical risk; its light weight makes it easy to carry in personal LOTO bags.
76 mm long shackle padlocks
For thick valve handles, wide hasp holes or situations where several parts must be locked at once, models with steel and nylon bodies and long hangers are used.
Dust-protected padlocks
DP models with cylinder-opening protection help keep the lock mechanism clean in dusty and dirty environments.
Color and key systems
Use colours to separate teams, shifts or subcontractors; with keyed-different, keyed-alike and master key options, build a structure that fits your LOTO program.
Padlocks with tag and personalization
By adding a name, employee number, department or photo label to the body, it is clear at first glance who the lock belongs to; for custom print requests, you can contact us.

- Shackle length: Measure the hole diameter and wall thickness of the device to be locked out; 38 mm is sufficient for most applications, and 76 mm is preferred for thick parts.
- Hasp material: At points with electrical hazards, use non-conductive options such as plastic or nylon.
- Environmental conditions: In areas with heavy dust and dirt, consider DP models that protect the cylinder.
- Color plan: Decide in advance which color belongs to which team, shift or subcontractor, and write it into the written LOTO procedure.
- Key arrangement: Choose keyed-different for personal padlocks and keyed-alike for team padlocks; use the master key only in a controlled and recorded manner.
- Quantity and storage: Allocate at least one padlock to each authorized worker, plan extra padlocks for workers at multiple points, and store padlocks neatly in LOTO stations.
Applications
Where Are Safety Padlocks Used?
Electrical panels
Circuit breakers are secured in the off position with breaker lockout devices.
Valves and pipelines
Ball, butterfly and gate valve lockouts are closed with a safety padlock to cut off flow.
Multi-person maintenance
With lockout hasps and group lock boxes, each team member adds their own lock to the same point.
Production lines
During machine maintenance, die changes and cleaning, energy isolation is secured with a lock.
How much do safety padlocks cost?
The price varies by hanging material, hanger length, key system, color/print preference and order quantity. For a current quote, you can message the product code and quantity to our WhatsApp line or call us by phone.
What distinguishes a LOTO padlock from an ordinary padlock?
A LOTO padlock is used only for lockout-tagout; it is lightweight, colour-coded and carries a warning marking, and its key cannot be removed until the lock is closed. Ordinary padlocks intended for property protection should not be used in LOTO.
Do lock colors have a fixed meaning?
No, there is no universal color standard; each company creates its own plan. What matters is that the chosen color scheme is defined in the written procedure and known to all employees.
How many locks should I give each worker?
The basic approach is at least one personal lock for every authorized worker. For people locking out more than one energy source at the same time, additional locks or a group lock box are used.
Should I choose 38 mm or 76 mm?
For standard circuit breaker, valve and hasp applications, a 38 mm shackle is usually sufficient. For thick handles, wide holes or the need to lock several parts together, a 76 mm shackle is more suitable.
What is the difference between keyed-alike and master key?
With keyed-alike, all locks in a group open with the same key. A master key lets an authorized manager open all locks and should be used under control and on record.
Can a name be printed on the lock?
Yes, a label or print with a name, employee number or department can be applied to the body. For customization options on bulk orders, you can contact us.
Safety Padlock Prices and Models
We have gathered the safety padlock models used in LOTO applications into a single catalog. Among steel-shackle, plastic-shackle, nylon-body and dust-protected options, you can easily find the padlock that fits your shackle length, material and color needs.
For companies setting up a lockout program, the color plan and key system are at least as important as the lock model. With keyed-different, keyed-alike and master-key alternatives, you can build a controlled LOTO structure at personal, team and supervisor level; you can personalize the locks with a name or department label.
Safety padlock prices vary by model, shackle length, key system and quantity, so instead of a fixed list we prepare a quote tailored to your needs. Just send us the product codes and quantities via WhatsApp or phone.
