In accordance with the "Regulations on Electrical Safety Work," and based on the actual needs of electrical production, electricians must wear safety helmets during various operations such as installation, maintenance, transformer substation work, construction sites, and repair workshops. These measures are crucial for ensuring the personal safety of workers. However, many safety helmets used on-site have hidden risks, and improper usage can lead to serious accidents. It's essential to address these issues carefully.
**1. Prolonged Use Without Replacement**
The recommended lifespan of a safety helmet is typically 2.5 years, as specified by the manufacturer. Yet, it's common to see helmets in use for over a decade simply because they look "new" or show no visible damage. Even if unused, helmets degrade over time due to exposure to environmental factors. Failing to replace them in time can result in failure during critical moments, leading to severe consequences.
**2. Using Helmets as Stools or Seat Covers**
Some workers use their helmets as temporary seats while traveling to job sites. This practice is dangerous because the primary function of a helmet is to protect against falling objects or impacts. Using it as a seat can cause structural damage, reducing its effectiveness. Moreover, this behavior violates safety protocols and may lead to legal repercussions.
**3. Poor Quality Helmets**
Not all helmets meet the required standards. Some lack sufficient impact resistance, have poor ventilation, or contain substandard materials like metal parts that can compromise safety. It’s vital to choose helmets that comply with national regulations, pass ISO certification, and have mandatory product certifications to ensure quality and reliability.
**4. Improper Storage Conditions**
Safety helmets should be stored in dry, well-ventilated areas away from heat sources and corrosive substances. The ideal temperature range is between -10°C and +50°C. Long-term storage without proper conditions can reduce the helmet’s lifespan. It’s best to purchase only what is needed and avoid stockpiling old inventory.
**5. Incorrect Usage**
Common mistakes include not securing the chin strap properly, failing to adjust the headband, or using damaged components. If the helmet shell or liner is damaged, it should be replaced immediately according to original specifications to maintain protection.
**6. Neglecting Pre-Use Inspections**
Before each use, check the helmet for cracks, deformation, or damage to the liner, cap hoop, and straps. Ensure all parts are intact and functional. If a helmet has been subjected to a heavy impact, it must be discarded immediately and never reused.
**7. Confusion Due to Mixed Management**
Some workers treat helmets as shared items, leading to disorganization and difficulty tracking expiration dates. This can result in the use of expired or damaged equipment. To prevent this, helmets should be numbered, assigned to individuals, and color-coded based on roles. A proper record-keeping system should also be maintained.
**8. Misunderstanding the Alarm Function**
Some helmets come with an electric field alarm that warns when near high-voltage equipment. While this adds an extra layer of safety, it shouldn’t replace essential safety procedures like electrical testing. Alarms may not activate at lower voltages or could be unreliable. Any alarm sound should be treated as a warning of potential danger.
It is important for all personnel to understand the correct use, maintenance, and limitations of safety helmets. Regular training and strict enforcement of safety protocols can significantly reduce the risk of accidents. Always prioritize safety—your life depends on it.
