Occupational Safety Training for Handheld Impact Wrench Operation

1. Overview of the Handheld Bolt Opener

a. What is a handheld bolt opener (bolt openers machine)?

A handheld bolt opener typically has a plug head or opening blade sized and shaped to fit the bolt or screw to be loosened. The user rotates the handle or plug head to perform the loosening operation, helping to remove them from the material or surface into which they are fastened.

Handheld bolt openers come in various sizes and designs to match the specific type of bolt or screw you are working with. This is a tool commonly used in construction, maintenance, repair, and other applications where bolts or screws need to be removed conveniently and quickly.

b. Operating principle of the handheld bolt opener

The operating principle of a handheld bolt opener is similar to that of a standard wrench. The handheld bolt opener is designed to generate a turning force to loosen bolts or screws by applying a rotational force to them. Below is how a handheld bolt opener works:

• Bolt or screw opening head: The handheld bolt opener has a head for opening bolts or screws. This head is designed to match the type and size of the bolt or screw to be removed. The opening head has teeth or blades to grip the bolt or screw securely.
• Rotating wheel or handle: The handheld bolt opener has a rotating wheel or handle that the user holds and turns. When you apply a turning force to the wheel or handle, it converts this force into rotational force applied to the bolt-opening head.
• Rotational force: The rotational force is generated by turning the wheel or handle. The bolt-opening head moves in the direction of rotation and applies torque to the bolt or screw, causing it to loosen from the material or surface in which it is installed.
• Applying force and direction of rotation: The user can control the amount of torque and the direction of rotation by adjusting how they apply force to the wheel or handle. This allows them to control the loosening of the bolt or screw as desired.

c. Industries that use handheld bolt openers

Handheld bolt openers are widely used across many industries and fields. Below are some manufacturing sectors and areas where handheld bolt openers are commonly used:

• Automotive manufacturing: In vehicle production, handheld bolt openers are used to assemble and disassemble bolts and screws on vehicle components, including engines, air-conditioning systems, and other parts.
• Machinery manufacturing: In the manufacturing of machinery and industrial equipment, handheld bolt openers are used to assemble and disassemble bolts and screws on mechanical parts and machine components.
• Construction: Handheld bolt openers are also used in construction and site works to install and remove bolts and screws on structural elements and construction equipment.
• Electronics manufacturing: In the production of electronic devices, handheld bolt openers are used for assembling and disassembling bolts and screws on printed circuit boards, electronic components, and other electronic products.
• Energy sector: Handheld bolt openers are used in the energy industry, for example in the assembly and maintenance of electrical and thermal systems.
• Maintenance and repair: Craftsmen, technicians, and maintenance workers use handheld bolt openers to dismantle, assemble and service equipment and machinery.
• Mechanical trades and DIY: Both individual users and mechanics use handheld bolt openers in DIY projects and personal workshops to remove and install bolts and screws.

2. Overview of the safety training course for operating handheld bolt openers

b. Training duration

Initial safety training duration

• Total training time is at least 24 hours, including examination time.
• 8 hours of theory on the system of policies and laws on occupational safety and hygiene
• 8 hours of theory on basic occupational safety and hygiene knowledge
• 4 hours of theory on specialized training content
• 2 hours of practical training on specialized content
• 2 hours for the final theoretical test at the end of the course

The safety training center will schedule the time into multiple sessions depending on arranging study time for workers. However, typically there will be 6 training sessions, the course runs for 3 days, assuming the manufacturing enterprise arranges continuous study time.

Periodic safety training duration

• Before the occupational safety card expires, if a worker wants reissuance they must undergo a periodic occupational safety training course, with the periodic training duration being at least 50% of the initial training duration.

Explanation: the total periodic occupational safety training time is at least 12 hours, including examination time. After completing the periodic course and passing the test, the worker will be reissued or have their occupational safety card extended.

d. Occupational safety card

After completing the occupational safety training course and passing the test, workers will be issued an occupational safety card (commonly referred to as a occupational safety certificate for group 3).

The group 3 safety card will display information such as full name, date of birth, the job and specific working environment. It will also include the training duration, an official red stamp and a signature confirming course completion.

According to the card issuance regulations specified in Clause 2 of Article 24 of Decree 44/2016/NĐ-CP, two cases are distinguished:

• If the employer and the employee have an employment contract with each other, then the employer must sign, stamp and endorse the safety card for the employee who completed the group 3 training from the occupational safety training provider and passed the test.
• In the case of freelance or seasonal workers who do not have an employment contract, the training provider must sign, stamp and endorse the safety card for the worker after they complete the training from the occupational safety training unit and pass the test.

3. Hazards When Operating a Handheld Bolt Opener

Operating a handheld bolt opener can cause a number of hazards if safety rules are not followed. Below are some common hazards when using a handheld bolt opener and how to avoid them:

• Injury from accidents: Using a handheld bolt opener without following safety rules can lead to injuries such as collisions, cuts, and wounds from the bolt opener or from bolts and screws.
• Bolts and screws getting stuck: Bolts or screws can become stuck in materials or surfaces, and trying to remove them can cause damage or injury.
• Loss of control: If the handheld bolt opener is not controlled carefully, it can become uncontrollable and cause collision or injury risks.
• Incorrect use: Using the handheld bolt opener incorrectly can cause damage or leave bolts and screws insecurely fastened.
• Unsuitable attachment heads: Using an attachment head that does not match the size or type of bolt or screw can cause damage to the bolt or screw and to the tool.
• Unintended cutting of surrounding materials: When removing bolts or screws, take care not to cut surrounding materials unintentionally. This can damage the tool and harm the product or materials.
• Pressure control: To control pressure and ensure not over-tightening or over-loosening, the operator must adjust the opening force and pressure applied to bolts and screws. This is especially important to avoid damaging bolts, screws, or surrounding materials.
• Eye and ear protection: Use safety glasses and hearing protection when necessary to protect eyes and ears from flashes, dust, and noise.
• Periodic maintenance: Perform regular maintenance on the handheld bolt opener to ensure it operates correctly and safely. Any malfunction should be repaired immediately.
