In accordance with the "Regulations on Electrical Safety Work" and the practical needs of electricity production, electricians must enter areas such as production and maintenance sites, high-voltage transformer substations, construction zones, and repair workshops, where elevated work is often required. This is a crucial measure to ensure the personal safety of workers. However, many safety helmets used on-site have hidden risks, and improper usage can lead to serious consequences if not addressed properly.
**1. Extended Use Beyond Recommended Lifespan**
The standard lifespan of a "non-defective" helmet is typically 2.5 years, as stated in the product manual. However, it's common for helmets to be used far beyond this period. Some personnel are even unaware of the risks, with some helmets remaining in use for nearly 10 years simply because they look new. In reality, even if unused, helmets degrade over time due to aging. Failing to replace them on time could result in critical failures during use, leading to severe accidents.
**2. Using Helmets as Seats or Stools**
This is a frequent issue, especially when workers wear helmets while traveling to job sites. Some people prefer to use the helmet as a seat rather than wearing it during transit, which is both unsafe and against regulations. The primary function of a safety helmet is to protect against falling objects, whereas using it as a stool offers no protection and may damage the helmet’s structure, reducing its effectiveness and lifespan.
**3. Quality Issues in Helmets**
Some helmets suffer from poor impact resistance, weak puncture resistance, inadequate sweat absorption, and poor ventilation. Additionally, the use of metal components can pose further risks. It is essential to choose helmets that meet national standards, have ISO certification, and are approved by relevant authorities to ensure their reliability and safety.
**4. Improper Storage Conditions**
Safety helmets should be stored in well-ventilated, dry areas, away from heat sources and corrosive substances. The ideal temperature range is between -10°C and +50°C. To maintain quality, it's best to purchase helmets only when needed, avoiding long-term storage that could reduce their effective lifespan.
**5. Incorrect Usage**
Common mistakes include not securing the chin strap properly, failing to adjust the headband to fit the user’s head size, and not replacing damaged parts according to original specifications. These errors can significantly compromise the helmet’s protective capabilities.
**6. Lack of Pre-Use Inspection**
Before each use, it is important to check the helmet for cracks, deformities, and damage to the liner, hoop, and straps. Any helmet that has suffered a major impact should be immediately discarded and not reused. Regular inspections help identify potential issues early and prevent accidents.
**7. Confusion from Mixed Management**
Some workers treat helmets as shared equipment, taking one whenever needed. This leads to disorganization, loss of manufacturing dates, and difficulty tracking expired helmets. To avoid these issues, helmets should be numbered, assigned to specific individuals, and color-coded based on job roles, with proper records maintained.
**8. Misuse of Near-Electricity Alarm Features**
Some helmets come with alarms that detect proximity to high-voltage equipment. While these can serve as an additional safety measure, they should not replace essential safety protocols like regular electrical checks. Alarms may not activate at lower voltages (e.g., 380 V), and some devices may be unreliable. If an alarm sounds, it should be treated as a warning of potential danger.
