Coating Protection
Published in Karan Sotoodeh, Coating Application for Piping, Valves and Actuators in Offshore Oil and Gas Industry, 2023
Masks that provide respiratory protection against dust come in three grades: filtering face piece (FFP) types 1, 2 and 3. These three levels of mask protection against dust are shortened to P1, P2 and P3. FFP1 or P1 dust masks provide the lowest level of protection against dust and provide protection against suspended solids and liquids in the air. FFP1 masks can be used for operations such as cutting and sandblasting with sandpaper. FFP1 can filter at least 80% of airborne particles. FFP2 provides a moderate level of protection against the dust created by sandblasting. FFP2 can filter at least 94% of airborne particles. FFP3 is the highest level of dust protection and can be used for handling hazardous powders and solids. FFP3 can filter at least 99% of airborne particles. In addition, there are three levels of respiratory protection against the gas from organic solvents: A1 (the lowest degree of protection), A2 (medium degree of protection) and A3 (highest degree of protection).

The PPEs most commonly used in EMS at respiratory, skin and mucous membrane protection level are: Respiratory: FFP2 and 3 (filter for particles) mask.Eye protection: goggles against the projection of particlesHand protection: nitrile glovesSkin protection: uniform, that after the observed risks the systematic use of long sleeves is recom-mended both in winter and in winter (mitigating the higher thermal load with suitable materials in the clothes).Foot protection, with safety boots with toe and reinforced sole to prevent pricking with needles and glass.
Control of Occupational Risks

The research conducted both in CIOP-PIB and in other scientific centers shows that to protect the respiratory system against nanoparticles, half-masks or complementary masks with class P3 filters should be used. In other cases and during short-term exposure, masks and half-masks with filters class P2 or FFP2 are allowed [Zapór 2012].

The present study warns coaches and weight lifters looking to improve RE performance that the use of FFP2/N95 face mask in both acute moderate (50% 1RM) and high-load RE routine (70% 1RM) increased RPE and decreased SPO2 in moderate load and decreased power in the high load. We believe that a negative effect on SPO2 and RPE during workout may decrease adherence to the exercise routine or discourage the use of a mask during training. Although FFP2/N95 masks appear to be more efficient than surgical and cloth masks for reducing the risk of Covid-19 infection, as they have better filtration and sealing capabilities (Kim et al., 2020; Liao et al., 2021; Sharma, Mishra, & Mudgal, 2020), surgical and cloth masks could also be used, since they seem less restrictive. However, further research is required to compare the effects of different kinds of face mask on RE and different intensity of exercise and if the impairing of performance observed acutely can occur in a chronic setting. If so, coaches and trainers should keep this in mind when organizing their training plan, in order to prevent a decrease in these variables and in performance during a workout.
Bench testing of noninvasive ventilation masks with viral filters for the protection from inhalation of infectious respirable particles

Health care workers exposed to infectious viruses such as SARS-CoV-2 need better respiratory protection. The U.S. Food and Drug Administration (FDA) recommends the use of N95 masks in health care settings for the protection of airborne particles since they are designed to achieve a very close facial fit and an effective filtration of airborne particles (FDA 2020a). In Europe, FFP2 or FFP3 (Filtering Face Piece) masks are recommended to protect health care workers from SARS-CoV-2 transmission (RKI 2020). Several countries have introduced a mask requirement in certain public areas for the general population.
