Protective glasses are a type of filter that changes the transmitted light intensity and spectrum. To avoid radiation damage to the eyes, the most effective and most common method is to wear protective glasses. The glasses can absorb light of certain wavelengths and let other wavelengths of light pass through, so they all have a certain color, and the color presented is the transmitted light color. One is for absorption and the other is for reflection. The former is used the most. Goggles are glasses that change the transmitted light intensity and spectrum to prevent radiation damage to the eyes. The glasses are divided into two categories, one for absorption and one for reflection. The former is used the most.

The welding mask is a tool that protects the safety of workers during welding and cutting operations. It is a high-tech product integrating optical, electronics, human science, materials science and other disciplines. The combination of high-quality LCD and plated glass is used as a light-shielding lens. The light-sensing system on the lens can detect the generation and disappearance of arc light during electric welding in an instant, and quickly drive the liquid crystal body to change color and light to achieve safe and effective filtering of harmful light, thus protecting the welder. Eyes and faces avoid arc radiation damage

Classification and use of earplugs
(1) Foam earplugs
Foam earplugs can reduce noise by around 30dB, which is best suited to prevent noise from entering the ear. For example, blocking noise on construction sites and blocking snoring while sleeping.
However, due to the simple design, wearing foam earplugs can make the sounds heard dull, so this type of earplugs is not recommended for those who want to hear high quality music under noise.
Earmuff prevent all sound from entering your ear and provide good noise reduction. Using these types of earplugs will mean that you will never hear the outside world.
If your job is to operate a large machine, it will emit high-intensity noise, and you don’t need to communicate with others when you work. Wearing a head-mounted earmuff to protect your hearing is very suitable.
(3) Silicone earplugs
Silicone earplugs have a certain noise reduction function, but in general its main function is waterproof, mainly suitable for swimming, or bathing.
(4) High fidelity earplugs
High-fidelity earbuds refer to music noise-proof earplugs with built-in acoustic attenuation filter that preserves high-quality music while reducing noise, typically reducing noise by around 20dB

The safety net is a protective net placed under or on the side of the high-altitude construction equipment installation or performance to prevent accidents caused by people or objects falling. The safety net consists of a net body, border ropes, tie ropes and tendon ropes. The net body is braided from a mesh rope and has a diamond or square mesh. The mesh size refers to the distance between two adjacent knots of the braid. The rope on the edge of the net body is called the border rope. The size of the safety net (nominal size) is determined by the size of the side rope; the rope that secures the safety net to the support is called a tie ropes. In addition, the ropes used to increase the strength of the safety net are collectively referred to as tendon ropes.
