Clean Room, Flow Hood and Bio-Safety Cabinet Certification


Adapt Certification Service, Inc. specializes in the certification of air flow and HEPA filter integrity of biological and chemical safety hoods/cabinets, laminar flow hoods, and fume hoods. We work with the medical, biotech and electronic industries. We also offer Viable and Nonviable Airborne particle counts for clean rooms and hoods, along with paraformaldehyde decontamination.

PASS or FAIL labels are installed on date of certification. Documentation of results are available 24/7 through our website’s password protected delivery system.

Decontamination services offered allow for the changing of HEPA filters or the safe movement of biological safety cabinets. After decontamination a certificate is affixed to the cabinet and a copy provided for your records.

Adapt Certification is owner operated, therefore you will work with a technician who is attentive to your needs.

Adapt Certification of Newark, CA, is centrally located to service in the Sonoma, Marin, San Francisco Bay and East Bay, Silicon Valley and Monterey Bay regions.

Adapt Certification Service was formed to fill the need for professional, quality-oriented certification of fume hoods, laminar flow equipment, biological safety cabinets & clean room partial counts.

The current owners have worked with the previous owner since 2001, in the design and fabrication of custom hoods, containment centers and rooms, through their first company, Tri City Plastics Inc., based in Newark, CA. The previous owner after 22 years, retired in early 2007, at which time the company was acquired.

The 25 plus years in custom fabrication and business experience of the new owners, combined with working with the previous owner in certification have made this a natural. This combination has advanced Adapt Certification into the 21st century.

Certification


HEPA Filter and Gasket Integrity

DOP (Dispersed Oil Particulate) testing utilizes a 10-20 mg per cubic meter concentration of polydispersed aerosol of PAO-4 (Poly-Alpha-Olefin) introduced upstream of the filter. The downstream side of the filter is then scanned with an aerosol photometer. Where scanning is not feasible a probe method is used. These tests ensure 99.97% filter efficiency at 0.3 nanometer particle size.


Air Velocity

Utilizing a precision thermo anemometer air velocities are checked to ensure proper operation of equipment per manufacturers recommendations, if required adjustments will be made.


Air Flow Patterns

A fog of DOP is generated to visualize airflow over work surfaces and at face of equipment. To reveal if a reflux is present endangering the work or personnel.


Viable Airborne Particle Testing

A viable particle is a particle that contains one or more living microorganisms. These can generally range from 0.2µm to 30µm in size. Testing is achieved by capturing, colonizing and counting colony growth. Adapt utilizes a nondestructive impaction BioCulture pump air sampler. The sampling head is engineered in such a way to deliver sampled air to a contact plate with a Soybean-Casein Digest medium or (Tryptic Soy Agar/Broth), so as not to disrupt normal ambient airflow and more importantly, without rendering the microorganism non-viable. The contact agar plates are then incubated at 20-25°C for 5-7 days and then at 30-35°C for 2-3 additional days. The resulting colonies are counted and reported. Each sampling location requires approximately 10 minutes.


Nonviable Particle Testing

A nonviable particle is a particle that does not contain a living microorganism but can act as transportation for viable particles.

Adapt Certification Services utilizes a Handheld Particle Counter able to detect particles of 0.30µm, 0.50µm, 0.70µm, 1.00µm, 2.00µm and 5.00µm in size.

Particle Counters do not distinguish between viable and non-viable particles but are much more technically advanced than air samplers. They consist of a sensor chamber containing a laser which uses mirrors and optics to view the particle, and a pump to pull the required sample through the sensor.

The principal behind the detection and sizing of particles is simple; the vacuum pump sucks the particle through the sensor chamber causing interaction with the laser beam. Deflected light from the laser is focused onto a photon detector which converts the light into an electrical signal that will vary in amplitude and quantity, resulting in sizing and counting of particles. The bigger the particle the more light it reflects and therefore the bigger the electrical pulse.

Each sampling location requires approximately 8 minutes.


Decontamination

Because of the nature of the work involved, Biological Safety Cabinets must be decontaminated when:

1. Any service work is performed within the contaminated portion of the cabinet, i.e. HEPA filter change.

2. Moving the cabinet from one location to another.

3. After initiating a totally different work program.

4. After a gross spill of a highly concentrated research agent.

Decontamination is accomplished by depolymerizing paraformaldehyde in controlled temperature and humidity to form a gas. The gas is then circulated throughout the cabinet and is then externally vented or chemically neutralized after an appropriate decontamination period.


Records and Reports

PASS or FAIL labels are installed on date of certification.

Documentation of results are available 24/7 through our website's password protected delivery system.

Once reports are completed an e-mail with your password and login information will be sent.


Biological Safety Cabinets

Biological Safety Cabinets (BSC) were developed because of the need for personnel protection not afforded by horizontal and vertical flow clean benches.

Like the clean bench, the BSC utilizes High Efficiency Particulate Air (HEPA) filters which have a 99.97% efficiency on particles of 0.3 micron size. There are three classes of Biological Safety Cabinets.

CLASS 1
The Class 1 Safety Cabinet is a modification of the chemical fume hood and provides protection to personnel and the environment, but little, if any, to the product.

Air is drawn through the work opening at a minimum average rate of 75 linear feet per minute (LFPM). The air is then exhausted through a HEPA filter. The Class I Cabinet can be used for low to moderate risk biological agents.

CLASS 2
The Class 2 Safety Cabinet was designed to provide personnel, environment and product protection. Product protection is achieved with the use of a supply HEPA filter, an exhaust HEPA filter and laminar (unidirectional) downward air flow. This minimizes air turbulence which prevents cross contamination in the product work area. Personnel protection is provided through a cabinet design that always maintains containment at the window opening.

There are four TYPES of Class II Cabinets. TYPES A1 & A2 and B1 & B2 are designed to recirculate a percentage of filtered air with the remainder being exhausted. TYPE A Cabinet is exhausted into the laboratory or externally. The TYPE B Cabinet must be exhausted through an external blower system. The third TYPE of Class II is a Total Exhaust Cabinet which, like the TYPE B, can be used with chemical carcinogens and low level radioactive materials. All three TYPES can be used for low to moderate risk biological agents.

CLASS 3
The Class 3 Safety Cabinet is a totally enclosed, self-contained, ventilated cabinet that operates at a negative pressure to the laboratory environment. Rubber gloves are attached and air enters through filters and is then exhausted through one or more HEPA filters. Incinerators are sometimes employed to provide greater protection to the environment.

Unlike the Class 1 and Class 2 Safety Cabinets, the Class 3 can be used for high risk biological agents, chemical carcinogens and low level radioactive materials.
