Is it allowed to take photos in the explosion-proof area of a chemical plant?

The principle is slightly different, but using a smartphone to take photos also carries the risk of becoming a source of ignition. Perhaps it is mainly to restrict the use of mobile phones

A explosion-proof phone will do; it’s quite easy to get one these days.

Production units establish so-called explosion-proof zones as special safety measures to prevent the continuation of related tasks in those areas under extreme conditions. The so-called explosion-proof zones can indeed be intimidating and frightening for ordinary people who are not professionals; in fact, most of the time, these areas are actually safer and more reliable than other places. It’s not as people think – it’s not filled with toxic, flammable, or explosive substances everywhere, so that one might die at any moment. . . It’s not that exaggerated. The purpose of establishing an explosion-proof zone is to instill in the workers a further mental reminder to be cautious and vigilant when working in this area – to be extremely careful and strict. In the explosion-proof areas of outdoor workplaces such as chemical plants and gas stations, it’s not that ordinary equipment cannot be used for photography; rather, taking photos in these areas under abnormal operating conditions is not allowed. For example, aging of equipment and pipelines can lead to minor leaks on a daily basis, with the resulting gases accumulating in dark corners within these explosion-proof areas. In bad weather, when the concentration of these gases becomes high enough, if someone happens to be in one of those corners and commits an action that violates the rules set for such areas, the consequences may fall on that person themselves or on many people around them.

Common issues with explosion-proof phone applications: 1. If an explosion-proof phone is physically damaged, it should not be used in flammable environments, as this can easily lead to explosions or fires； 　　2. When installing explosion-proof rechargeable batteries, handle them with care and avoid pressing or knocking on them, as this can undermine the battery’s explosion-proof properties; ensure that the labels on the batteries are clear and legible ； Ensure that the contact points are clean and that there is no dirt inside the compartment. Place the rechargeable battery in its proper position, make sure the sealing ring around the battery compartment is level, and then secure the battery cover with screws. Apply even pressure to each screw – it should not be too loose nor too tight. The rubber ring should be compressed to an appropriate size ； 　　3. Explosion-proof phones must not be used in areas where the required explosion-proof rating is not met; otherwise, safety accidents may occur due to the failure to meet the specified explosion-proof standards ； 　　4. Explosion-proof phones should not have their batteries replaced in an environment filled with flammable gases; otherwise, static electricity generated during disassembly can cause spark discharge, leading to explosions or fires ； 　　5. The operating temperature range for explosion-proof mobile phones is –20°C to +40°C, with a standard air pressure of 80Kpa to 110Kpa ； 　　6. When using explosion-proof phones, it is necessary to maintain the readability and consistency of the markings; in addition, it is important to ensure consistency in the labeling of the device’s own information, so as to determine the true identity of the device ； 　　7. Explosion-proof phones should not be charged in an environment with flammable gases; use the charger provided by the manufacturer for charging ； 　　8. When an explosion-proof phone develops common faults or it is suspected that such faults exist, it should no longer be used. Contact the manufacturer immediately for repair and calibration. Under no circumstances should one attempt to disassemble the phone on their own, as this will alter the original design structure of its hardware, resulting in the loss of its explosion-proof capabilities ； 　　9. Strictly comply with the standards specified in the explosion-proof certification regarding the use of external devices connected to mobile phones and mechanical equipment ； 　　10. It is not necessary to store explosion-proof phones for long periods in humid, cold, or hot areas.

Explosion-proof phones address the issue of open flames in various ways. Their appearance is similar to that of ordinary phones, but the materials used and their physical properties differ significantly from those of regular models; typically, PVC flame-retardant materials are employed. Manufacturers employ a variety of explosion-proof techniques, such as intrinsically safe circuits, limiting the ambient temperature of the enclosure, and using \"dust-tight\" or \"dirt-resistant\" enclosures to prevent dust from entering, in order to prevent flammable substances from being ignited and ensure that explosion-proof devices can operate safely in such hazardous environments.

It’s better not to. In July this year, Haining in Zhejiang held a hearing on the security of \"scan-to-pay\" systems at gas stations, during which experiments were conducted on \"mobile phone electromagnetic radiation\". After discussion, the expert panel from Haining, Zhejiang, concluded that \"using mobile payment near fuel pumps poses security risks.\" Hasn’t there always been debate about whether it was possible to use mobile phones at gas stations in the past? It’s even more so in chemical plants. I’ve been using Asunex’ s products; I use them for taking photos and making calls, and so far they seem to be quite reliable. Alas, thousands of people have suffered in Lebanon this time! Heartbreaking! It’s better to spend a little more money on safety~

It’s really necessary to take photos, and in accordance with the regulations for hot work, the necessary procedures for carrying out hot work must be followed.
