TWA, total dust 5 mg/ m3, 8 Hr. As you can see from this screenshot, dust is dispersed and accumulates in the air and on surfaces. Polystyrene foam insulation has unique properties differentiating it from . inhalation: remove to fresh air. This process generates large amounts of PU dust. It is resistant to acids, alkalis, salts, mineral oils, organic acids, and alcohols 41. Styrene - Hazard Recognition | Occupational Safety and Health ... PDF Polystyrene Material Safety Data Sheet Cas No 9003-53-6 The US reduced its safety exposure limit to 0.3 parts per million - seven times lower than the British limit. Runoff from fire control or dilution water may cause environmental contamination. PDF Fentanyl Fact Sheet Ver-1-05-22-18-ok - US EPA TWA, respirable dust. skin contact: wash with soap and water. Comparing the results of virgin (non-radiated) polystyrene sample with that of UV irradiated polystyrene sample for 60 minutes (1 hour), it is clear that the intrinsic viscosity was reduced from 0.490 to 0.379, the molecular weight was reduced from 108473 to 71694, and the number of session per polymer chain was increased to 0.513 respectively . However, user-generated dust may pose a physiological hazard if inhaled or ingested. Avoid breathing vapours, mist or gas. Extruded Polystyrene Foam Insulation Issue Date: 09/04/2015 Page 3 of 10 Unusual Fire and Explosion Hazards: Mechanical cutting, grinding or sawing can cause formation of dusts. Expanded Polystyrene (EPS Foam): Uses, Structure & Properties Difference Between Polypropylene And Polystyrene One method used to limit these exposures is to spray water that contains surfactants to capture the airborne particles near the mining face. Polystyrene has a good optical property like it is a transparent polymer allowing high transmission of all . Fumes/vapors released Inhalation Only dust produced from machining EPS or small particles are likely to be inhaled. . The polystyrene melting point is 240 degrees Celsius. MIE testing are done around this concentration. Styrene is a colorless, flammable liquid, which has a sweet odor and is highly volatile. Those working with or cutting Styrofoam should be aware of these hazards. Polystyrene-specific gravity is 1.054. 20045162 - Centers for Disease Control and Prevention Exposure may aggravate those with p re-existing eye, skin, or respiratory conditions. PDF Safety Data Sheet - Styrene Products These microscopic sized particles enter and deposit deep within the lungs leading to impaired lung functioning and possible lung disease. Dust explosion concentration - PowderProcess.net . All these values are in air only, please note that the presence of flammable gas will totally change results. Some liquids produce vapors that may cause dizziness or asphyxiation. Potential toxicity of polystyrene microplastic particles Ingestion Always wash hands before eating, drinking or using the toilet. Its chemical resistance is nearly equivalent to the material upon which it is based - polystyrene. One of these ways is to avoid inhalation of its dust particles. . Polystyrene (9003-53-6) - Listed on the United States TSCA (Toxic Substances Control Act) inventory
