Electrical safety is a crucial concern in every home and workplace. When it comes to portable appliances, one common question arises: Can I perform PAT testing myself? PAT testing, or Portable Appliance Testing, is the process of checking the safety of electrical appliances. While it may seem tempting to save money and do it yourself, there are important factors to consider before taking on this task. In this article, we explore the ins and outs of DIY PAT testing and provide you with essential information to make an informed decision.
- Businesses have a duty of care to ensure the safety of employees, visitors, and the public, including the maintenance of personal equipment used for work.
- While there is no legal obligation to be a qualified electrician for PAT testing, competent staff can perform visual inspections in low-risk environments.
- Greater knowledge and experience are needed for combined inspections and testing, along with proper testing equipment and understanding of hazards.
- It is recommended to take a PAT testing course and gain a Certificate of competence to become a PAT tester.
The Importance of Portable Appliance Testing
PAT testing is an important process that should be considered when dealing with electrical appliances or equipment. It involves a comprehensive inspection and testing to ensure the safety of an appliance or equipment before it’s used. The first step is to carry out a visual inspection to check for any wear or damage.
It’s also important to inspect the plug, ensuring that it has no damage and verifying the wiring and correct fuse rating. Once these have been checked and approved your equipment will need further testing by a PAT tester. This testing procedure will identify any faults with the insulation resistance, earth continuity, double insulation, lead polarity, etc. Once all components pass their tests, a PAT label will be attached displaying their test results for future reference.
Is PAT Testing A Legal Requirement?
Although PAT testing is not technically required by law it offers an excellent form of protection for businesses who wish to maintain their responsibilities under UK legislation.
Taking all necessary steps to guarantee safety and avoid injury or damage can prevent potential legal action from being taken against a company or landlord if an accident were to occur due to ineffective checks or faulty electrical equipment. Businesses and landlords should take every precaution possible to ensure they comply with legislation and maintain a safe working or living environment.
Who Is Responsible For PAT Testing Electrical Equipment?
The responsibility for electrical appliance safety ultimately lies with the employer or landlord. Businesses of all sizes must take reasonable steps to ensure their employees are safe from harm when using electrical equipment in the workplace, and similarly, landlords are responsible for creating safe conditions for their tenants. Employers have the duty to meet safety standards, identify and assess any potential hazards posed by electrical appliances, and put adequate systems in place to prevent accidental injury or damage.
In larger businesses, where more complex procedures and stringent regulations apply, employers may appoint a ‘competent person’, whose role is to make sure that the company meets relevant safety legislation. This person should be trained and qualified in carrying out risk assessments, maintaining any necessary documentation such as test records, and ensuring repairs are carried out only by competent personnel who possess appropriate qualifications.
Can I PAT Test My Own Electrical Appliances?
Technically, you can test your own electrical appliances. However, competent knowledge of electricity is essential. Although you can complete PAT tests yourself, the legal responsibility will be placed on you if anything goes wrong, which it’s best to seek the assistance of a professional who can complete both visual checks and internal checks.
The level of knowledge you need to be able to PAT test electrical equipment is significant and is particularly difficult if you are responsible for an entire workplace. Therefore, delegating the work and hiring a qualified electrician to carry out PAT tests is the best solution.
How To Complete Your Own PAT Test
If you have confidence in your own PAT testing abilities, have attended electrical training courses, and think you are ready to complete your own PAT tests, here is a 10-step guide to carry out electronic tests:
- Ensure you have the necessary equipment: A portable appliance tester, a socket tester, labels, and a log book.
- Identify the appliances that need to be tested: Make a list and gather them in one location.
- Inspect the appliances for any visual signs of damage or wear: Pay attention to the power cords, plugs, and any exposed wires.
- Plug in the PAT testing machine and the socket tester into a known working power outlet.
- Connect the appliance to be tested to the PAT testing machine using the appropriate lead or adapter.
- Select the appropriate test on the PAT testing machine for the appliance and follow the instructions provided with the machine.
- Conduct the necessary electrical tests such as earth continuity, insulation resistance, and leakage current.
- Record the results of each test in the log book or on the appliance label provided.
- If the appliance fails any of the tests, mark it as failed, and remove it from service until it can be repaired or replaced.
- Once safety testing is complete and all appliances have been labeled, store the equipment properly and ensure the testing area is clean and tidy.
How to Identify Equipment That Requires PAT Testing
There are three different classes of appliances that need PAT testing. Below is a quick breakdown of each one.
Class One Appliances
Class one appliances typically refer to electrical appliances that require grounding or have a grounded metal casing. These appliances have a basic level of insulation and include a grounding wire to protect users from electric shock.
Here are some examples of Class 1 appliances:
- Washing machines
- Electric stoves and ovens
- Microwave ovens
- Electric kettles
- Clothes dryers
- Toaster ovens
- Power tools (e.g., drills, saws, etc.)
- Vacuum cleaners
Class Two Appliances
Class two appliances, also known as double-insulated appliances, do not require a grounding wire because they have additional layers of insulation to protect users from electric shock. These appliances are designed in a way that even if there is a fault in the insulation, the user is still protected from coming into direct contact with live parts. They often only need a visual examination as opposed to a full user check.
Here are some examples of Class 2 appliances:
- Mobile phone chargers
- Laptops and tablets
- Hair dryers
- Electric shavers
- Handheld power tools (e.g., handheld drills, jigsaws, etc.)
- Audio players (e.g., portable speakers, headphones, etc.)
- Desk fans
- Blenders and food processors
- Electric toothbrushes
- LED desk lamps
Class Three Appliances
Class three appliances are the safest class of appliances as they operate on low voltage and pose a lower risk of electric shock to the user. However, you might need to test the charging leads that come with these devices for safety reasons.
Here are some examples of appliances that fall under this classification:
- Mobile phone chargers
- Cameras (such as digital cameras)
- Portable electronic devices (e.g., MP3 players, portable gaming devices)
- Handheld GPS devices
- Bluetooth speakers
- E-book readers
- Portable electronic notepads or tablets
