                                          INTRODUCTION

This document identifies risks to health and safety and proposes control measures for the BES field
course, ENV 3102 Environmental Challenges: Asian Case Studies II, to be held 16 to 31 May, 2019, on
the island of Bohol, in the Philippines. It was drafted following steps outlined by the Canadian Centre
for Occupational Health and Safety (CCOHS), which describes the aim of the risk assessment process
as: “to remove a hazard or reduce the level of its risk by adding precautions or control measures, as
necessary.” This document also adheres to the guidelines of the NUS Office of Safety, Health and the
Environment (OSHE), in its Trip Safety Guidelines, available here.

Risk assessment for most field activities was conducted through a reconnaissance trip by both
original BES lecturers (Drs J Coleman and J Hastings) to Bohol in April, 2013, when most legs of the
journey were completed and many locations visited – identified by the initials JC and JGH. Later trips
have been conducted by JC (March, 2014, November 2015) to assess more legs and locations – these
are identified by the initials JC. The most recent trip was conducted by JC and Sorain Ramchunder
(SR). However, certain aspects of the trip may not have yet been experienced and properly recced.
These aspects or activities bear no initials, but instead include an explanation for why no recce was
done and list measures taken to minimise risks. In addition, this assessment does not cover risks
associated with activities that participants undertake of their own volition, i.e., during free time.
These risks are not foreseeable. Participants can do as they please during free time, with the
understanding that those activities are at the participants’ own risk and that students must respect
certain rules, including advising staff of their whereabouts and remaining contactable (to be
discussed during intro days). On the last day of the trip (30 May), everyone, including staff, has free
time, so students who choose to undertake activities on that day may not have the support of
staff, should anything happen, and they must be prepared to look after themselves.

To assess risks resulting from interactions with dangerous plants and animals, JC conducted
extensive research to collate information from reliable sources. For information on dangerous
plants, local scientists and institutions were consulted, e.g. Bohol Biodiversity Complex. Below is a
list of sources from which information was garnered, mostly regarding animals. The OSHE Field Trip
Safety Manual further supports the information collected.

                             HOW TO USE THE RISK ASSESSMENT TABLES

Working out the ‘significance’ of a hazard involves determining the two contributing factors: the (1)
likelihood and (2) severity. Meaning, for any identified hazard, what are the (1) estimated probability
that it will occur and (2) likely consequence if it does occur? Although the precise terms used to rate
likelihood and severity may vary among assessments, good practice dictates that they be clear,
concise and consistent within an assessment and easily understood by the reader.

This assessment consists of a series of tables – one per activity or section of the field trip. Each risk
associated with an activity (leftmost column) is rated according to its likelihood (L; 2nd column) and
severity (S; 3rd column). It is standard practice to implement risk controls (4th column) until controls
for the hazard in the yellow zone (medium risk) are as low as reasonably practicable, or the hazard is
in the green zone (low risk). However, this assessment goes a step further and proposes controls
even for some hazards already in the green zone. Hazards without a colour are too variable in risk
and/or severity to place accurately, but control measures still exist.

This assessment uses these abbreviations and definitions for the likelihood and severity of hazards.
                Likelihood                       Severity
VL = very low   Rare: not expected to occur,     Negligible; unlikely to cause injury, ill‐health or
                but still possible               much hassle / stress
L = low         Remote: unlikely to occur        Minor; injury or ill‐health requiring first‐aid only
                under normal circumstances       (e.g., minor wounds, bruises, irritation, sprains, ill‐
                                                 health with temporary discomfort); hassle / stress
M = moderate Occasional: possible or known Injury requiring medical treatment or ill‐health
                to occur                         leading to disability (includes lacerations, burns,
                                                 minor fractures, dermatitis)
H = high        Frequent: common                 Serious injuries or life‐threatening disease
                occurrence                       (includes amputations, major fractures, multiple
                                                 injuries, acute poisoning)
VH = very high Almost certain: continual or      Catastrophic; fatality, fatal diseases or multiple
                repeating experience             major injuries

     Likelihood VL                  L                   M               H                 VH

In all cases, it is the responsibility of the course coordinator(s) to audit control measures on a regular
basis. This is done annually, and the audit involves reviewing the risk assessment and noting details
of non‐compliances and corrective measures.

A5. Road transfers to various field sites – JC
    Charter vehicles (bus + van) are hired (HNU and/or Felys Transport) to transport all participants, except when we stay at Bohol Biodiversity Complex (BBC),
    which uses its own field vehicles to take us short distances. JC has worked with all providers and driven all the routes (maps in Appendix A). Most distances

D1. BBC‐based accommodations
    We spend a total of 3D/2N at BBC. Because there is no one facility in the area large enough to accommodate the entire group, for the purposes of lodging,
    we may split up among three locations: BBC, RDJ Mountain View Resort and dorms at Bohol Island State University (BISU). We have stayed at BBC and RDJ,
    but not BISU (has not been recced), but it is literally adjacent to BBC. Also, BBC is upgrading / changing its accommodations and facilities, so we do not know
    exactly what to expect. Information here is compiled based on all our observations. There will be at least two staff members at each location.

                                                E – SNORKELING PREPARATION AND IN‐WATER ACTIVITIES – JC
To minimise risks, JC selected a major tour operator (MRS; see tables A4 and C1) recommended by local contacts, and there is plenty of supervision (minimum of
five staff). To further minimise risks, staff supervisors are good swimmers, only half the students (25 maximum) go out on the water at any one time, and there
are five MPA wardens with us, giving a minimum supervisory ratio of 2.7 : 1.

  Problems on entry,        L         M         To some extent, measures dependent on boat operator’s own control measures.
  e.g., landing on                               Understand the possibility of boat hitting one’s head when hanging onto the mooring rope.

  drifting away                                  If waves / current present, link arms with others to avoid drifting away.

  Being hit by a boat       VL        VH        To some extent, risk minimised because wardens are keeping watch on water surface.
  while snorkelling                              Always snorkel in pairs and remain in the area designated by staff.
                                                 Stop snorkeling every 2‐3 minutes to check location.

  Lightning strike          VL        VH        If lightning is sighted or emergency whistle is heard, evacuate the water immediately.
  Getting lost              L         L–H       Attendance‐taking is much more important with water‐based activities.
                                                 Buddy system is employed – never swim alone.
                                                 NUS staff double‐check that everyone is always accounted for, especially when leaving.
                                                 Everyone taught the distress signal, to be used also if swimmer/pair has drifted too far from the boat to swim
                                                   back easily. Participants may also use their whistle to call for help.
                                                 Stop snorkeling every 2‐3 minutes to check location.

Drowning               L   VH   All students complete declaration of swimming ability.

                                 Students who declare that they cannot swim must have vest inflated or participate in stationary fish survey
