Respiratory protection


Recognizing the danger of breathing

Respiratory protection: protection

For your present and later health is pure, clean air is essential. Since your workplace may well cause situations that are detrimental to your respiratory system and your health, wearing a respiratory protective device is recommended.

These dangers are often not clearly recognizableso you should be aware of the proper use of the selected protection device.

Dust, smoke and fog

These pollutants are solid airborne particles. The most dangerous are so small that they are no longer visible to the naked eye. You can get into your lungs and from there into the bloodstream. This will be acute or long-term damage caused. These particles are: dust, the z. B. by crushing, milling or grinding; Mist in the form of drizzle; Smoke when welding or work that requires high temperatures.

Gases and vapors

The effects on your health range from temporary disturbances of consciousness to serious acute or permanent damage. In too high a concentration they are deadly. This is especially true when they displace the oxygen and too Erstickungsanfälen to lead. Gases are distributed particularly well and quickly at room temperature. Often, gases are generated during chemical processes and during high heat. Vapors can occur where cleaning with solvents or painting is done.

lack of oxygen

Oxygen deficiency is when the oxygen content (normal: 21%) in the air drops below the minimum value of 17%. It occurs in confined areas that are not adequately ventilated, and is caused by chemical reactions or fire, or by gas that displaces oxygen.

Extreme temperatures

Extremely high or low temperatures can damage your respiratory system. They can occur in blast furnaces or in freezer procedures.

Dangers to breathing

The more you know clean fresh air and all the dangers to breathing, the better you can protect your respiratory system at work. Even if the air looks clean, that does not mean it's really clean. The dangerous substances are all too often invisible to the eye. If you know it, you can protect yourself even better.

Dust, smoke and fog

  • dust arises when solid substances are comminuted, such as when grinding or grinding. The smaller the dust particles are, the longer they stay in the air and the more likely you are to inhale them.
  • smoke occurs when metal is melted, evaporated and then cooled rapidly, e.g. when welding. This process produces very fine particles that float in the air.
  • fog consists of tiny droplets that are normally produced during spraying. The droplets may contain toxic, solid substances in dissolved form.

Clean Air

Healthy clean air consists of several components: 21% oxygen (O2), 78% nitrogen (N2), and 1% is a combination of various other gases. At rest, inhale about 10 liters of air per minute. At work or under load, the air requirement increases many times over.

  • Oxygen deficiency occurs in closed areas whenever the percentage of oxygen is too low. Oxygen deficiency can be caused by a chemical reaction or fire, or by a gas that displaces oxygen.
  • Extremely hot air can be a hazard depending on the temperature and the time during which you are exposed to this air.
  • Extremely cold air can also be a hazard depending on the temperature and the time during which you are exposed to this air.

Effects of dangers

Inadequate protection may cause hazardous substances in the air to damage your respiratory system and internal organs. Atenschutzgeräte are to be used in particular when the hazardous substances occur in concentrations, so that the natural defense systems of your body are no longer able to compensate for the damaging effects.

Dust, smoke and fog

Dust, smoke and mist can irritate the nose, throat and upper respiratory system. Some particles can enter the lungs depending on their size and type, where they can damage the lung tissue and cause more serious health problems.

Gases and vapors

Gases and vapors can enter the lungs directly. There they enter the bloodstream and can damage the brain and internal organs in this way.

lack of oxygen

Lack of oxygen can lead to dizziness, heart palpitations and headaches. Lack of oxygen can damage the brain and cause cardiac arrest after a few minutes.

Extreme temperatures

Very hot or very cold air can damage the nasal, cervical and lung mucosa or impair normal breathing.

The natural defense of the body

Your body has a fabulous respiratory system to deliver air and oxygen to the lungs and eliminate depleted substances. Even when you are in normal fresh air, the natural defenses of your body are constantly active, purifying and filtering the air.

  • nose hairsThe first zone of protection is the rough hair in your nose. They hold larger particles while breathing.
  • cilia: Cilia are the tiny hairs in your respiratory tract that move about 10 to 12 times a second to deliver mucus and captured particles back to your throat for swallowing or coughing.
  • mucous membrane: Your entire respiratory tract is covered by a mucous membrane. Particles that pass through the nasal hairs are trapped in the mucous membrane and transported out again by the wave-like movement of the cilia.
  • Normal breathing: Your nose warms, cools and moisturizes the air you breathe. Your upper airway carries air into the lungs. Its lower airway branches like a tree and ends in tiny bläxhen called alveoli. From there, the oxygen passes into the blood, while used air from the blood flows back to the lungs and is exhaled.
  • cough reflexCoughing is a protective reflex that helps to remove mucus and foreign bodies that have lodged in your respiratory system.

Operation of respiratory protective equipment

Maintenance-free half masks filter the breathing air. These respirators are constructed of non-woven materials that trap the hazardous particles or contain additional materials that are effective in retaining gases and vapors.

  • Filtering half masks: Filtering half-masks offer you protection against particles and / or gases and vapors, but require no special care and maintenance. As with all data protection devices, it is important that they are properly seated and properly worn and handled during use. Only then are the mouth and nose safely protected from harmful substances.
  • protection targetDepending on the construction, filtering half-masks protect against damaging particles and / or gases and vapors. Choose your respiratory protective device according to the work you have to do. Maintenance-free half-masks do not protect against lack of oxygen. Consult your supervisor for special protection restrictions on your respirators.

Functionality of protective masks

When you inhale, the filter media in the filter cartridge will catch particles, gases, and fumes before they enter your airways. In order for your respirator to function properly, it is important that you use the appropriate filter cartridge for the type of hazardous substance and respirator in question.

  • Half masks with interchangeable filters: Like half-masks, these half-masks cover the nose, mouth and chin. The air is purified through various filters for particles, gases and vapors, which can be exchanged after consumption. You do not have to throw away the mask after use because all parts are interchangeable.
  • Schutzziel: Half masks can reduce the specific hazards of particles, gases or vapors in your work area to a safe level. The label indicates against which type of hazardous substance the filter cartridge protects. Before using your respirator, make sure you have read and understood all instructions for use. Nonduitable half masks with gas filter cartridges do not protect against lack of oxygen.

Adaptation

Only a properly worn respirator can protect you. Therefore, pay close attention to the manufacturer's instructions for use. If the device is in more sizes, choose the one with the best fit. This way, face shape, whiskers and certain skin types can prevent a good fit. Therefore, before using any respirator, fittings are required.

  1. Form the metal bar with your hands so that it adapts to the bridge of your nose and sits perfectly.
  2. Adjust the side straps of your respirator to ensure a comfortable and secure fit.

Negative pressure test

  1. Place your hands on the mask body and breathe in jerkily. You should feel that the mask is nestled against your face.
  2. Close the opening of the exhalation valve with your hand and exhale lightly. You should feel a rising pressure in the mask.

Care of your respirator

Be sure to check your respirator for damage before entering a hazardous area. Follow the practice of your company when cleaning and storing your respirator. Clean your respirator as described in the instructions for use. Store in a suitable container. As gas filters lose their effectiveness through use, replace them if you notice any ingress of contaminants during use. Notify your supervisor if the respirator is in need of repair.

  • Torn ribbons
  • Deformations or cracks
  • Defective valves

Easy-care breathing apparatus

Filtering half masks do not require cleaning. If you feel your breathing has become more difficult, or if you notice a peculiar taste or smell, you should renew the mask.
