10.1 Environmental Biosafety and Containment Practices for Agarwood Research

Purpose:

  • Protect researchers, workers, and the environment from accidental exposure to microbes, chemicals, and genetically propagated plant material.
  • Ensure safe and sustainable propagation, inoculation, and resin induction practices.

1. Biosafety Levels (BSL) for Agarwood Work

LevelTypical ActivitiesSafety Requirements
BSL-1Plant tissue culture, handling non-pathogenic fungiStandard lab coat, gloves, basic lab hygiene
BSL-2Handling Fusarium oxysporum, Lasiodiplodia, or dual-action formulationsBiosafety cabinet (Class II), PPE, decontamination protocols
BSL-3Genetic modification or work with unknown pathogenic microbesControlled access, HEPA-filtered airflow, specialized lab rooms (rare in agarwood labs)

Note: Most agarwood propagation and inoculation work is BSL-1 or BSL-2.

2. Laboratory Containment Practices

A. Personal Protective Equipment (PPE)

  • Lab coat, gloves, and safety glasses
  • Masks or respirators when handling powders, spores, or aerosols
  • Closed-toe shoes

B. Work Area

  • Use biosafety cabinet for fungal inoculation or tissue culture
  • Maintain clean bench and sterilized instruments
  • Avoid eating, drinking, or personal items in lab

C. Equipment Sterilization

  • Autoclave media, tools, and culture vessels
  • Sterilize work surfaces before and after experiments with 70% ethanol or other disinfectants
  • Properly dispose of contaminated waste (autoclaving or chemical disinfection)

3. Environmental Containment in Field Work

A. Fungal Inoculation

  • Apply dual-action formulations in controlled tree wounds
  • Avoid runoff into soil or water bodies
  • Use biodegradable plugs or sealants to prevent environmental contamination

B. Waste Management

  • Collect excess inoculum, resin residues, and plant material
  • Treat with autoclave or chemical sterilants before disposal
  • Prevent release of fungal spores into the surrounding ecosystem

C. Field PPE

  • Gloves, long sleeves, and masks during inoculation
  • Minimize direct contact with inoculated wounds

4. Chemical and Solvent Safety

  • Handle solvents (ethanol, hexane, methanol) in fume hoods
  • Store chemicals in labeled, fire-resistant cabinets
  • Use proper containers for volatile or toxic solvents
  • Spill kits and first aid equipment should be readily available

5. Recordkeeping and Traceability

  • Maintain logs for fungal strains, inoculum preparation, and application sites
  • Label all experimental trees and batches clearly
  • Record dates, personnel, and biosafety measures followed

6. Training and Awareness

  • Train staff on biosafety levels, PPE, and spill response
  • Conduct periodic safety drills and audits
  • Ensure staff are familiar with local regulations for microbial and chemical handling

7. Regulatory Compliance

  • Follow national biosafety guidelines (e.g., Philippine BMB, DENR, DOH)
  • Obtain permits for use of microorganisms in field applications
  • Ensure sustainable and safe agarwood production while preventing environmental contamination

8. Summary of Best Practices

  1. Work under appropriate biosafety level (mostly BSL-1 or BSL-2).
  2. PPE and hygiene are mandatory in labs and field sites.
  3. Contain microbial inoculants to avoid environmental release.
  4. Sterilize tools, media, and waste before disposal.
  5. Document all procedures and maintain traceability.
  6. Train personnel on chemical safety, fungal handling, and spill response.
