Ensuring comfort within your Cleanroom

Monitoring of temperature and humidity control within a Cleanroom is essential to reduce microbial growth and control static build-up, as well as ensuring employee comfort.

Relatively humidity (RH) influences a number of factors that could degrade the overall cleanroom performance, including: 

  •         Bacteria growth
  •         Static charge build-up
  •         Metal corrosion
  •         Moisture condensation
  •         Water absorption
  •         Photolithographic degradation;
  •         Personnel Comfort

Humidity also impacts particle control: High humidity can cause staff members to sweat, and in low humidity conditions, static electricity can affect the movement of particles. For example, when it is too dry, any residual particles on labels or supply packaging will stick to gloves and other surface. Higher humidity also becomes oppressive; humidity lower than 30% leads to dryness, cracked skin, respiratory discomfort and unhappy personnel.

A 40% to 60% range in RH minimises the impact of bacteria and also falls well within the personal comfort zone. 

Selecting the right cleanroom apparel for maximum comfort

Individuals shed particles more rapidly when sweating or shivering. A staff member who is too hot is more likely to take gowning shortcuts, while a staff member who is too cold is more prone to wearing inappropriate garments for a the controlled environment. A comfortable cleanroom temperature is directly related to the extent of gowning required.
