chemicals released during laser cutting
laser cutting uses high-voltage electricity to generate high temperatures, and the concentrated laser beam evaporates the material according to a predetermined path through the cnc software system, thereby forming the corresponding object shape.
throughout the processing process, some chemicals and by-products are produced as waste. here, we briefly look at the chemicals produced when laser cutting acrylic.
methyl methacrylate (mma)
the properties of methyl methacrylate and the health effects of exposure to this chemical are given below.
• methyl methacrylate is a colorless liquid with a sweet taste
• commonly used in acrylic plastics, adhesives, coatings and resin production
• skin contact may cause irritation, redness and dermatitis in those with sensitive skin
• even short-term exposure to concentrated mma can cause respiratory tract
• mma is also considered a potential carcinogen
now, it is necessary to learn and follow the exposure limits and regulations for laser cutting acrylics.
osha and acgih have established exposure limits and guidelines for mma to protect workers from a variety of health effects. osha's permissible exposure limit (pel) for mma is 100 ppm. the acgih threshold value (tlv) for mma is 50 ppm, which is an 8-hour twa.
formaldehyde
understanding the health hazards and carcinogenicity of formaldehyde will definitely help you stay safe. it is a colorless gas with a unique odor. the health hazards that may easily result may be,
• inhalation of gas can cause eye irritation. additionally, the nose, throat, and respiratory tract are common hazards of exposure
• repeated and long-term exposure to formaldehyde can lead to serious illnesses such as asthma and bronchitis, as well as allergic reactions
• the international agency for research on cancer (iarc) and the national toxicology program (ntp) classify formaldehyde as a known human carcinogen
to reduce the hazards caused by this chemical, osha and acgih have developed regulatory guidance.
osha's permissible formaldehyde exposure limit (pel) is 0.75 ppm, and acgih's formaldehyde threshold value (tlv) is 0.3 ppm (8-hour twa). osha also sets a short-term exposure limit (stel) for formaldehyde of 2 ppm. understanding regulatory guidelines for all operators is critical.
hydrogen cyanide (hcn)
this is a highly toxic element found in the production of materials containing coatings and additives. certain coated acrylic products can generate hcn. when cutting acrylic, the high temperature of the laser produces decomposition products such as cyanide.
this chemical element is highly hazardous to health. therefore, safety measures for acrylic laser cutting are a must.
inhaling hydrogen cyanide vapor can cause symptoms such as headache, dizziness, nausea, vomiting, difficulty breathing, and even loss of consciousness and death in severe cases. to minimize the possibility of any health problems, make sure to take the following steps:
appropriate ventilation systems and personal protective equipment (ppe), monitor performance and provide workers with adequate knowledge training.
health risks associated with acrylic fumes
ignoring the importance of safety precautions and failing to comply may result in serious bodily injury. prolonged exposure to hcn may cause death.
respiratory effect
• irritation and discomfort: exposure to fumes and gases and inhalation of irritants such as methyl methacrylate and formaldehyde can cause acute respiratory irritation.
• long-term health effects: long-term exposure to acrylic fumes can cause respiratory diseases such as bronchitis, asthma and chronic obstructive pulmonary disease (copd).
skin and eye irritation
• contact dermatitis: exposure to acrylic fumes can cause contact dermatitis. symptoms of contact dermatitis may include redness, itching, swelling, and blistering of the skin.
• eye irritation and damage: continued exposure to laser radiation can cause eye irritation and damage.
safety precautions for laser cutting acrylic
safety precautions are essential to reduce the likelihood of accidents when laser cutting acrylics. follow safety measures and ensure a safe working environment. some important safety measures are,
✔ make sure the cutting area is well ventilated to remove fumes and gases.
